Brand's ex warns him to be careful with Perry

London, (ANI): 'Despicable Me' star Russell Brand's ex-girlfriend has said that his flirtatious attitude might land his relationship with Katy Perry in trouble. Brand and Perry are engaged and set to tie the knot soon.

"He never seemed like a guy who could stick to one woman," the Sun quoted her as saying. "I hope he doesn't make the same mistakes he did with me, but if he does he's a bit of an idiot. I hope he sticks to being good and doesn't mess about because she's obviously an amazing girl," she added.

Georgina Baillie's fling with Brand ended when he famously exposed her on Radio.
