Meet Luke Littler’s VERY glamorous older sister Caitlin: 17-year-old darts prodigy’s primary cheerleader will help him by this yr’s championships

After dealing with a ‘very upsetting’ break-up from his older girlfriend Eloise over the summer, Luke Littler will be needing all the support he can get from his inner circle as he prepares to take on the World Darts Championships this weekend. 

Luckily, Luke, 17, will have his glamorous older sister Caitlin firmly by his side for the duration of the tournament. 

Though she tends to shy away from the bright spotlight of her younger brother’s sudden fame, 22-year-old Caitlin has been by his side at matches from the start and is his number one cheerleader. 

Like Luke, who captivated the nation through his love of celebrating his darts wins with a kebab and playing on his Xbox, Caitlin also appears to lead a relatively normal life in their hometown of Warrington, including nights out with friends and watching Love Island with her mother Lisa and pet bulldog Nala. 

But the stunning blonde will also bring a touch of glitz and glam to the darts matches, and has racked up 27,000 followers on TikTok with glimpses into her sociable lifestyle.

Beauty queen Cait has previously admitted to bleaching her naturally brown hair and getting lip filler to achieve her desired look.  

‘No way thats Luke littlers sis,’ commented one viewer on her TikTok account, noting the apparent lack of resemblance between the siblings. 

Indeed, culture and branding expert Nick Ede previously told The Sun that Luke and Cait could even be set to become the ‘next Furys’ – as her sparkling presence and his fame as current world number 4 have the ingredients to become reality TV‘s next big hit. 

When ‘Luke the Nuke’ first took the world of darts by storm in January, the nation was captivated. 

For not only was Luke only 16, but he seemed a very unlikely candidate for Britain’s next sporting hero – having a relatively normal upbringing in Warrington with his parents, brother and sister. 

Cait has been by Luke’s side from the start and, with their brother Leon, the siblings were all very close growing up. 

She has frequently shared selfies with her brother to Snapchat, while posting in support of him whenever he takes part in a match. 

In May, when Luke won the premier title, Cait told her Facebook friends she was the ‘proudest sister ever’. 

She wrote on Facebook: ‘I actually have no words, what a birthday present! Proudest sister ever. 

‘Everyone’s probably getting bored of me sharing posts about Luke but I can’t stop he’s just too good.’ 

Back in January, when Luke reached the PDC final, she added: ‘Can’t even begin to put into words how proud I am of you Luke, we all love you so much and cannot wait to see what else you can achieve. You are amazing and this is just the start, Woww running out of words, so proud.’

She shared a sweet photo of her hugging her brother in celebration – while reposting everything she could see in support of him on X, formerly Twitter. 

Following his victory over Brendan Dolan in the quarter-finals of the 2023/24, Caitlin supported her brother again, writing: ‘The dream continues. Unbelievably proud of you.’

Writing in August after he won his second Modus Super Series gong she said: ‘Speechless he’s done it again! Never EVER been more proud of someone, what a night! You just continue to amaze us all everyday we all love you so much, keep smashing it.’

She is known to accompany him to his matches – with Luke often tagging her on Facebook afterwards. In one, he wrote: ‘I wouldn’t be here if it wasn’t for these amazing people,’ giving a touching nod to his supportive family members.  

Cait’s Instagram is relatively low-key – as despite having 10,000 followers she has no posts and is set to private. 

However her boyfriend Jack Cookson has posted a series of loved-up snaps of the two of them together, including bowling and mini golf dates. 

In December 2022, Jack shared a sweet message to his Instagram story to reflect on their past year together, writing: ‘Happy new year, just want to say thank you to this gorgeous girl for coming in my life and helping me find myself again. 

‘I’ve had such a s*** year and she has been hands down the best thing to ever happen to me I love her more than anything.’ 

It appears Luke and Jack are also close, with Jack joining in his hug with Cait at the PDC final in January. 

In October last year, Luke wrote on Facebook that he was hanging out with his sister and Jack in Portsmouth, saying they were off to get some ‘scran’ and go on the arcades after a lie in. 

Glamorous Cait regularly shares clips of her fashionable and skimpy outfits to her TikTok account, attending festivals and going on nights out with friends. 

She has admitted to having lip filler, posting on TikTok: ‘When someone says they have a picture of me with brown hair, no lip filler and block eyebrows’, accompanied with a sound in the backdrop saying ‘burn it’. 

Luke is seen by many as the best teenage sporting talent since Wayne Rooney burst onto the scene in 2003 – so it’s no surprise his family has also attracted interest.

At just 17, Littler has won 10 senior PDC titles, and is the reigning Premier League Darts, Grand Slam and World Series Finals champion. 

Famously, he opted for a ‘cheeseburger and chips’ after missing out on the world championship to Luke Humphries in January last year. 

The known kebab lover has become a cultural phenonemon, achieving a level of fame not usually acquired by darts players. 

He even encouraged what became known as ‘Littlermania’ – after a record high of 3.7 million viewers watched the 2024 PDC world final, which PDC president Barry Hearn attributed to Littler’s success. 

He signed a deal with BoohooMAN in February, even appearing on the Jonathan Ross show alongside Raye and Millie Bobby Brown. 

However, he and his now ex-girlfriend Eloise Milburn came under fire after going public with their romance in January, due to their age difference. 

Milburn was a constant presence at his big matches since he broke onto the scene with his run to the PDC World Championship final at the start of the year. 

Littler, 17, and Milburn, 21, saw their romance previously blossom over a 10-month period with the Warrington-born icon’s rise to stardom thrusting both into the public eye. 

The pair began dating just weeks before the start of the World Championship last December and shared a holiday to New York together alongside other darts stars and Littler’s parents, Lisa and Anthony. 

However, the pair split over the summer, with Luke later posting on his Instagram story to say: ‘Everyone needs to stop sending hate towards Eloise saying it’s here [sic] fault this and that.

‘I myself split up with Eloise and everyone just needs to give us some time, no need for everyone to message her and give her grief.’

It was revealed that Littler was left ‘very upset by the situation’, according to reports.

Explaining the emotions after the breakup, a source told The Sun: ‘Luke and Eloise have broken up and it is still very raw. He is naturally very upset but they have agreed to stay friends.’

Littler and Milburn previously displayed their public affection for each other both at matches the teenager was competing in and on social media.

Milburn – who plays darts at an amateur level herself – was a keen follower of her partner’s career and Littler would frequently approach her to give her a kiss following his wins at the oche.

However, the pair also faced criticism over the age gap between them with Littler later revealing he had hired someone to run his Instagram account who deletes such comments before he can see them.

Milburn previously explained she had found it difficult coping with the abuse surrounding the issue over their ages, by telling the Guardian: ‘It was tough to start with.

‘The first day I let it get to me a lot. But you learn that as long as the pair of you are happy, that’s all that matters. The people that matter most are supportive of us.’

The pair are believed to have ended their relationship on good terms and will remain friends despite no longer being romantically involved.

Stress was put on the relationship due to Littler’s hectic schedule since his meteoric rise in darts that has also led to him becoming a social media and online star.

The pair have previously streamed themselves playing games online together, while Littler has also featured in several videos alongside the likes of Youtube star KSI.
