When you're on the Riviera at this time of year, there are so many famous and beautiful faces around it's hard to stand out from the crowd.

But Lily Allen managed it - thanks to a shock of peroxide hair, a skimpy bikini and a sultry pose.

The 23-year-old singer revealed her new blonde look at the exclusive Hotel du Cap - Eden Roc in Antibes on Tuesday, the eve of the opening day of the Cannes Film Festival.

With the world's media watching out for A-list celebrities, Miss Allen stripped down to her bikini bottoms to sunbathe on the terrace of the hotel, where she is staying with friends.

Located just along the coast from Cannes, the hotel is a favourite with Hollywood's big-hitters.

At one point, she was spotted frolicking in a water front pool with a group of male companions.

The Smile singer made the most of the clear blue sky, sunbathing in a tiny bikini, and showing no reservations as she peeled off her top.

Lily is among a stellar crowd flocking to the South of France ahead of the Cannes Film Festival this week including Hollywood heavyweights Brad Pitt and Angelina Jolie.

Her decision to holiday during the high-profile festival indicates that she is still determined to revive her presenting career despite failing to win ratings with her chat show Lily Allen and Friends on BBC3.

She is also said to be working on a TV comedy with Gavin & Stacey stars Mathew Horne and James Corden.

Corden, who rumoured to have shared a romance with the singer in recent months, apparently encouraged her foray into sketch writing.

A source told The Sun: "James loves her ideas and shares her sense of humour. He reckons the humour from Lily's first album, 'Alright, Still' will come across on the small screen.

"If they can recreate the laughs they have together at the pub it should be interesting to hear how their stuff turns out."

The performer has had a difficult year so far after suffering a miscarriage in January and splitting from boyfriend Ed Simons from band the Chemical Brothers.

She blamed the stress of her TV show for making her go up three dress sizes to a 12 but said recently she was determined to slim down for the summer.

As these pictures show, her efforts have paid off.
