Lily Allen shows off her eye-catching rainbow bob as she goes for lunch with her ex-boyfriend Seb Chew in LA

She's known for playing around with her style, especially her hair and on Friday, Lily Allen was showing off her recently dyed hair.

The 29-year-old singer debuted the new look on Instagram last week as a 'last hurrah' before turning 30 and was still happily rocking the kaleidoscope style when she went for lunch in Los Angeles. 

The Hard Out Here singer was out and about with her friends, including her ex-boyfriend Seb Chew with the pair remaining close buddies since their split years ago.

Lily was keeping things casual for her bite to eat and as well as her now slightly fade 'do, she added a sweatshirt printed with a tribute to the late Aaliyah.

The top had a 90s style Tommy Hilfiger-style design with Aaliyah Baby written across it along with an image of the singer, who tragically died in a plane crash in 2001. 

She teamed the old-school sweat with a simple pair of grey skinny jeans and some white platform high-top trainers.

Lily shielded her eyes from the bright LA sunshine with a pair of reflective sunglasses.

At one point her hair which she described in her Instagram post as 'watermelon', became too hot around her neck and she tied it up into a short ponytail.

Puffing on her cigarette she and her friends made their way from the car to Joan's café for a bit of food.

She was joined by friend and ex-boyfriend DJ Seb Chew who she dated for two and half years before splitting back in 2007.

The pair have remained close friends and are often seen together.

She's currently in Los Angeles recording music, and is also thought to be house-hunting over there to relocate with her husband Sam Cooper and their daughters Ethel Mary and Marnie Rose.

She also recently toured the States, and also mingled with Hollywood's finest at pre and post-Oscars parties in mid-February, in honour of the most prestigious movie awards ceremony of them all.

Lily may also have another incentive to stay in California, as recent reports claim that she is in talks to star in the second Fifty Shades Of Grey movie.

The Daily Mirror reports that she recently met with director Sam Taylor-Johnson at Hollywood's Chateau Marmont, where it is said they chatted for 90 minutes about a possible role.

A source said: 'They were definitely making some plans. They are friends, and move in the same circles in London, they're in that trendy set. Lily would be the perfect person to work on the next Fifty Shades movie.'

However, when contacted by MailOnline, a spokesperson for Lily said that the claims were untrue.

Lily has been in Los Angeles working on her new music, but her profile is thought to be ideally suited to starring in the next movie based on the erotic novels by E.L. James.
