Cara Delevingne goes topless in sexy bikini to celebrate 25th birthday with friends in Mexico

British supermodel and actress Cara Delevingne celebrated her 25th birthday in style with her model girl friends in a lavish Mexican getaway.

The Suicide Squad actress, who turned 25 on 12 August, enjoyed a fun-filled outing on the beach with her girl pals - including the likes of models Suki Waterhouse, Jaime Winstone and Georgia May Jagger - as she tried her hand at paragliding.

According to the Daily Mail, Delevingne was spotted flaunting her model figure in a skimpy grey bikini and was even pictured topless, giving her fans an eyeful of her assets and numerous tattoos. Other A listers celebrating included her sisters Poppy and Chloe Delevingne, Adwoa Aboah, Alice Dellal, Lady Clara Paget and socialite Mary Charteris.

The fun-filled activities for the girls included swimming in an underwater cave, frolicking with whale sharks and going on a jungle ride in an ATV. A source told MailOnline: "The Mexican premiere of Valerian marks the end of the movie's promotional tour so Cara has, very generously, decided to fly out 20 of her best girlfriends for the adventure of a lifetime."

Revealing the star-studded guest list, the insider said: "She's invited all her closest friends, including Kendall Jenner, Suki Waterhouse, Georgia May Jagger, Jamie Winstone, and, of course, her older sisters Chloe and Poppy."

The source continued: "The girls will be trekking in the rainforest, kayaking and going on excursions to sample the varied wildlife of the region... all finished off with a massive party to celebrate Cara's birthday at the end."

"It's a girls-only trip and Cara wanted to celebrate a busy few months of hard work and get away from it all as much as possible with those closest to her. It's going to be an incredible trip," the insider described her Mexican lavish vacation.

The Valerian and the City of a Thousand Planets actress also shared several photos of herself and her model friends as they stripped to sexy bikinis for a boat day. She captioned the image: "I am so lucky to have such incredible friends thank you for inspiring and supporting me ladies #Sexico "
