Christina Applegate: 'Pregnancy Made Me A Little Cuckoo'
Christina Applegate The star, who has beaten breast cancer, appeared on a US talk show with a sweatshirt stuffed under her dress to emphasize her pregnancy.
She told host Jimmy Kimmel that it would be more exciting for the audience to see a baby bulge.
She said: "Everything you read in the baby books, I've got. The cravings, the morning sickness, the psychosis.
"You kind of go a little cuckoo. Yelling for no reason, that kind of thing.
"It's almost like you're stepping outside of yourself and you see this insane monster. And you want to stop her but she's also kinda funny to watch."
She said she and her Dutch-born fiancé Martyn Lenoble had not yet chosen a name for the baby.
Christina voices a character in the new movie Cats and Dogs: The Revenge of Kitty Galore.
