Brooklyn Beckham sits on curb outside posh LA restaurant, leaves separately from wife Nicola Peltz

Brooklyn Beckham looked lonely as he sat on a curb outside of a posh Los Angeles restaurant as he left separately from wife Nicole Peltz amid claims she is feuding with his famous mother Victoria.

The 23-year-old aspiring chef was pictured all by his lonesome seated cross-legged on the curb while tapping away on his cell phone outside Cecconi’s West Hollywood on Sunday night.

He reportedly had arrived with his 27-year-old actress wife for the dinner at the fine dining Italian eatery but was solo as he left the dinner as there have been reports of a feud between Nicola and Brooklyn’s 48-year-old fashion designer mom.

The eldest of the Beckham kids looked casual cool in a plain white T-Shirt with black trousers and grey Adidas Yeezy 750 high-top sneakers. 

This comes as his mom Victoria reached out to congratulate him on a recent joint interview with wife Nicola – but failed to mention her daughter-in-law amid feud claims.

The fashion designer took to Instagram on Friday to share an image from his Vogue Hong Kong spread, excitedly writing: ‘So proud!!’ before tagging her son and the publication and adding a pink love heart.

While David, 47, also uploaded another image of their eldest child and wrote ‘looking good Bust’, with Victoria also sharing the same message.

However, despite Brooklyn, 23, taking part in a joint interview and photoshoot with his new wife, 27, his mother failed to acknowledged her participation. 

Both Nicola and Brooklyn also shared a selection of images from their shoot including the cover to their respective Instagram accounts.

But while Victoria liked the solo image of her son, she failed to click like on the cover featuring both Nicola and Brooklyn.

While she also didn’t share any love on the images Nicola posted to her own Instagram. 

Despite this, the fallout with daughter-in-law Nicola, which has strained her relationship with son Brooklyn, has reportedly left Victoria ‘heartbroken’.

The former pop star is concerned over how it will affect her closeness with the photographer-turned-chef, and is said to be ‘distraught and fearful’, it has been reported.

Mrs Beckham has relied on her eldest child for support while her football-playing husband travelled the world, and their relationship has previously been described as ‘inseparable’, according to Mail+.

The cold war began when Nicola Peltz and Mrs Beckham clashed over her wedding dress and the Transformers star accused her new mother-in-law of stealing the limelight at her wedding. 

The Beckhams have refused to pay for Brooklyn’s US green card, a source claims, and, most recently, the one-time Spice Girl snubbed her son and daughter-in-law for her new Paris Fashion Week show, says another family insider.

Though the newlywed chef and Transformers actress are happy and fawning over each other, trouble has been brewing between their two houses.

A source who knows Nicola well says that the drama began around her and Brooklyn’s Palm Beach, Florida, wedding – and has only escalated.

As a celebrity designer, many in the fashion world assumed Victoria, 48, would be designing Nicola’s wedding dress. But instead, the bride appeared on the May cover of Vogue in Valentino couture.

Nicola later gave an interview insisting that ditching Victoria’s offer was not designed to be a slight against her new mother-in-law.

‘I was going to and I really wanted to, and then a few months down the line, she realized that her atelier couldn’t do it, so then I had to pick another dress,’ she told Variety last month.

But one insider said Nicola, 27, ‘never’ intended to wear Victoria Beckham at her wedding.

‘She was always just going to let her design something. But she was never going put that on her,’ the source said. ‘She has too many actually talented designer friends.

‘It’s like when you have an in-law, and they say they make the best meatballs, you hate meatballs, but you let them cook it anyway. That’s exactly what happened.

‘She was never, ever going to wear it.’

Another source with knowledge of the dress controversy was led to believe Nicola really was considering wearing her mother-in-law’s design, but was left in the lurch at the ‘last minute.’

‘Valentino was concerned that they didn’t’ have enough time to do the dress because Victoria didn’t tell the Peltzes that her atelier couldn’t make the dress for Nicola until the last minute,’ the second source said.

After the dress drama unfolded, Nicola became offended when David and Victoria’s close friend ​​Marc Anthony gave a gushing speech at her wedding – all about Victoria, according to one insider.

‘It was totally just an ode to Victoria and how awesome she is. Nicola loves to be the center of attention, especially on her wedding day. So this really, really p***ed her off,’ the source said.

‘She stormed off in the middle of her wedding reception with [sister] Brittany and her mom, and was crying her eyes out.’

Another source agreed Nicola was upset during the reception – but said it wasn’t because Anthony was gushing about Victoria.

This insider claimed that Posh Spice stole the newlyweds’ First Dance song for her own mother-son dance moments before Brooklyn and Nicola were meant to two-step in front of their guests.

The First Dance song was Anthony’s ‘You Sang To Me’. The romantic love song includes the lyrics ‘Now I’m crazy for your love’, ‘When I called you late last night you see I was falling into love’ and ‘Girl, I live for how you make me feel’. 

A source at the wedding told DailyMail.com: ‘Marc asked Nicola and Brooklyn to pick their favorite song to dedicate to them, and that one was their favorite.’

‘Nicola left the room because she and Brooklyn thought Marc was introducing them for a special dance to a love song the couple had chosen,’ the second source said.

‘But without any warning and at the request of Victoria, Marc switched it to a mother-son dance using the same song.

‘Most of the guests could tell something off had happened. It was uncomfortable for the couple who were thinking it was to be a special moment for them.’

This insider also claimed that Grammy-winning Latin pop star Anthony was paid a handsome sum by the Peltz family to appear and perform with a band, despite his close friendship with David.

A source close to the Peltzes claimed that Nicola was upset over the alleged song-stealing, and not Marc’s speech.

‘Brooklyn and Nicola knew Marc Anthony was close to the Beckhams and would of course be complementary to them in his talk. If Nicola had been concerned about that, her father would not have paid to have Marc Anthony and his band perform,’ the source said.

Meanwhile, amid tensions in his family, it’s been reported that Romeo Beckham is acting as peacemaker to ‘smooth over’ the alleged feud.

The footballer, 20, is said to be attempting to repair the fractured relationships between his mother Victoria, brother Brooklyn and sister-in-law Nicola by acting as a mediator between the three.

A source told The Mirror: ‘There is tension between the families and Brooklyn is torn down the middle. He feels conflicted and the result is he and Romeo have become much closer. Romeo has been his shoulder to cry on and his rock.’

They added: ‘Romeo has been on the end of the phone to his brother ­morning, noon and night. He has also been talking to Nicole to try to smooth over the situation.

‘It’s awful for Brooklyn that his marriage has started out with so much stress between his mother and his new bride. Nicole has demanded loyalty from him at all costs.’

MailOnline have contacted Romeo’s representatives for comment.
