Wasting away: Kate Lawler appears shadow of former self as she hits beach in bikini

Just two months after running the London Marathon, Kate Lawler appears a shadow of her former self.

The 2002 Big Brother winner looked dangerously thin as she soaked up the sunshine on a Spanish beach last week.

A fit and athletic Kate, 28, was recently pictured running the marathon wearing only Ann Summers lingerie to raise funds for the Cystic Fibrosis Trust.

But despite downing a pint of beer, there was no sign of a beer belly as ultra-slim Kate headed for a swim in a skimpy black bikini.

Kate's body shape has fluctuated since coming out of the BB house as the 5ft 7in star's weight at one point dropped down to 8st 8lb.

The DJ reportedly refuses to eat carbohydrates in the evening and trains four to five times a week at the gym.

Kate said: "I've always been a big eater but I stay skinny because I'm so active. I never have dessert but I can't resist bread."
