Driver: 'I need weights on my bum'

Minnie Driver has claimed that she needs weights on her bottom to keep her standing up straight since she became pregnant.

The singer admitted during a concert last week that she was struggling to wear heels and not fall over since her stomach and chest increased in size.

Speaking onstage in LA, Driver said: "I've lost my balance - my boobs and my stomach are huge, and you can't wear high heels unless you weight your bottom or something!"

The Good Will Hunting actress confirmed she was pregnant in a interview with Jay Leno last month.

Driver has refused to reveal the father of her child to date.
