Minnie Driver's baby bump is making her lose balance and preventing her from wearing high heels.
The 'Grosse Pointe Blank' actress - who has so far refused to reveal the identity of her baby's father - was performing tracks from her new album 'Seastories' in Los Angeles on Saturday night when she made the revelation.
She 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!"
Minnie - who recently admitted she has been craving olives - also said her appetite hasn't increased as much as she thought it would.
She added: "I haven't wanted to eat as much food as I think I want to eat! I'm not as hungry as everyone told me I'd be!"
However, the 38-year-old actress is determined not to let the baby - who she revealed is due in August - stop her from fulfilling any professional obligations.
She said: "I'm going to tour in France, Germany, Norway, Switzerland and England - and I'm going to do a movie with Uma Thurman! I'm really hoping I've got the stamina, but I know how to take care of myself!"
