"never worries" about her weight.
The 'Commander' hit maker admits she is currently heavier than usual but insists she doesn't want to get too skinny because she loves her curves too much.
She said: "I would never want to lose too much weight. I love having curves and a bum. Men like something to hold on to. I'm nearer the top end of my weight range at the moment, though I was heavier when I went to the Grammy Award s a few years ago, but everything is in the right place! I'm working the long, lean look.
"I'm around a UK clothes size 8, but sometimes a 10 or even 12 in bottoms depending on where I shop. But I never worry about it."
The former Destiny's Child star also admitted she would never rule out having cosmetic surgery when she gets older.
She said: "If my butt is falling I'm going to pick it up. I'm not against it. I'd never have Botox though - no way. I like to have expressions."
