Pregnant actress Minnie Driver looked just swell as she revealed her growing baby bump at a film premiere in Los Angeles last night.

Dressed in a cleavage-revealing baby-doll blouse, and matching black trousers, Minnie, 38, cut a sleek figure, even with her swelling bump at the premiere of film Street Kings at Grauman's Chinese Theatre.

Revealed: Minnie Driver unveiled her growing baby bump on the red carpet in Los Angeles last night, but she is still reluctant to reveal who's the daddy

Flying solo: pregnant Minnie has a busy summer ahead - with a tour promoting new album Seastories

The British actress, 38, revealed her pregnancy in a blaze of publicity including an interview on US chat show Tonight Show with Jay Leno.

And last month on talk show Ellen, she revealed she was hoping for a girl.

However, the Good Will Hunting star has remained tight-lipped regarding the identity of the baby's father. Despite being asked by Leno who the father was, Driver declined to reveal his name.

But she appears to have embraced going solo while pregnant declaring she'll spend the summer "fat and happy".

But she admitted that there is one part of the process she could do without.

"I don't know why they call it morning sickness. I am sick morning, noon and night...but it's a fair trade off", she joked.

The 38-year-old has a busy couple of months coming up - she has released an album, Seastories in the UK and is touring Europe, Hawaii and LA.

But after that, Driver said, she'll be getting in plenty of pre-baby rest and relaxation.

"I'm just going to have the summer to be fat and happy," she said.
