Minnie Driver is taking cues from other celebrity moms, revealing she's pregnant after a crack about her weight (like Lisa Marie Presley), making the announcement on late night TV (like Britney did when she was expecting Jayden James), and is keeping mum about who the father is (like Northern Exposure's Janine Turner).

The 38 year old Oscar nominee said she's four months "and a little bit" and has been plagued with the dreaded morning sickness that lasts all day.

In addition to an impressive acting resume, Driver has released two albums, Everything I've Got in My Pocket and SEASTORIES. Audio samples of her songs are available on her website.
