She is the sister of a very famous Hollywood actor and is also renowned for starring in Sex Lives Of College Girls.

The actress, 32, who welcomed her first child in October, is the older sibling of the famous A-lister who has starred in various award-winning films.

Her younger brother sparked a social media frenzy when he arrived to the Golden Globes with his billionaire reality star girlfriend.

The American-French actor, who has received various accolades, is known for starring in Wonka, Dune and Little Women.

The A-lister’s sister looked a far cry from his short brunette locks as she attended The Sex Lives of College Girls’ advance screening of season 3 in New York on Wednesday.

So, can you guess who her famous brother is?

It’s… Timothée Chalamet!

Timothée’s older sister Pauline, 32, looked completely uncrecognisable as she attended the screening of a brand new series that she stars in.

Pauline and Timothée, whose parents are Marc Chalamet and Nicole Flender, both went down a career route into acting.

Pauline is best known for her portrayal of Kimberly in the HBO Max series, Sex Lives of College Girls.

The show follows four 18-year-old freshman roommates at Essex College in Vermont.’

An IMDb synopsis describes its characters as ‘a bundle of contradictions and hormones’ who ‘are equal parts lovable and infuriating.’

Pauline recently welcomed her first child with longtime partner Rhys Raiskin. The new mother hasn’t revealed the baby’s name, gender, or exact birth date.

Timothée has been dating billionaire-beauty mogul Kylie Jenner, 27, for over a year – first confirming their romance in September 2023.

Kylie first ignited dating rumors with Timothée in April 2023.

While they have not yet made their red carpet debut together, Kylie attended the 2024 Golden Globe Awards as Timothée’s date and also made a surprise appearance at the L.A. premiere of his film.

In October, Kylie had the support of Timothee’s big sister Pauline as she walked for Coperni during Paris Fashion Week.

Moments after Kylie’s catwalk debut, she was spotted sharing a hug with Pauline, 32, at the Coperni after-party, which was held at the theme park.

In video shared by NSS Magazine, Kylie looked excited to see Pauline as she flashed a huge smile before pulled her in for a hug.

In August, a source told DailyMail.com exclusively that Kylie is so focused on the relationship and spending time with Timothee that she has become ‘incredibly detached’ from her inner circle.

‘Kylie is turning into her brother Rob [Kardashian] – she is choosing to be a homebody for the most part,’ insiders revealed to DailyMail.com.

‘For Kylie, it is her family, her kids and then obviously she is all in on hanging out with Timothee.’ 

Kylie is said to have lost all interest in trying to keep up appearances with industry pals as the insider continued: ‘Time for going out and doing the Hollywood friendship thing is long past her. She is 27 going on 70. 

‘What suits her now is being out there when she needs to be, not because she wants to be. She is so busy with her relationship and being a mom and a businesswoman.’

The source added: ‘She doesn’t miss her times in the Hollywood shuffle and her desire to have friends outside her bubble isn’t anything she is interested in right now.’
