British pop star Lily Allen fears she is a terrible girlfriend, because she constantly has to be the centre of her lover's attention. The smile singer was treated for depression aged just 17 after splitting from her first love, and has undergone behavorial therapy to address the problem. But the 21-year-old still concedes that dating her is not something to be taken lightly. She says, "Boys make me mental. I'm really bad and attention-seeking and not a particularly nice person in relationships. "Say I ring my boyfriend and he's in the pub having a laugh with his mates, I won't be able to stand it and I'll start crying so he has to come and find me."
