British supermodel Jodie Kidd sparked rumors about her pregnancy after showing a little bump beneath her T-shirt at an A-list party last Saturday.

 The 28-year-old blonde showed up at the event with her fiance, internet entrepreneur Aidan Butler, to see live performances from Sting, Jamiroquai, Pharrell Williams and Busta Rhymes, reports British Vogue.

Kidd, who once said she would love to have many children, announced her engagement to Butler last summer, three months after she started dating him, but said they would wed after her sister Jemma marries Arthur, Earl of Mornington.

The bash, celebrating the launch of the new Gizmondo game, music and phone console, has assembled the likes of Jasmine Guinness, Saffron Aldridge, Jade Parfitt, Rachel Stevens and Lennox Lewis.
