London: Playboy model and actress Kelly Brook is going be a proud mother of a baby girl with her boyfriend Thomas Evans.

The actress said she is expecting her first child with Thomas, whom she started dating just four months back.

The 31-year-old British beauty tweeted on a social networking site, “Thomas and I are happy to announce we are expecting a baby girl. We are delighted”.

Brook and the 25-year-old former rugby player were first seen together during her London birthday celebrations in November last year.

She's been capitalising on her increasing profile in the US since her bikini-clad appearance in successful schlock-horror 'Piranha: 3D' in which she did an underwater scene.

Brook who is famous for her natural curves, has dated Hollywood stars Jason Statham, Billy Zane and rugby player Danny Cipriani and 'Glee' star Matthew Morrison.

Brook was in news last year after she received half-a-million USD for her Playboy shoot.
