After once claiming she was "not comfortable" being seen in swimwear, Kelly Osbourne has had the last laugh by landing the cover of Shape magazine in nothing but a bikini. The reality star has lost than more than 3st 5lb (50lbs), which she is celebrating by appearing in a two piece swimsuit for the American publication.

"I used to eat chips and cookies and drink soda all day long. I had to start making better choices," she reveals, crediting her Dancing with the Stars partner Louis van Amstel for her transformation. "He made me eat turkey burgers and salads. Then I started losing weight and realised, "Oh, it's true what they say: Diet and exercise really work!"'

The new issue of Shape is out November 22.
