18 Hot Pregnant Celebrity Mamas of 2007

Halle Berry
Due date: March

Best known for: Being the first African-American to win the Best Actress Oscar

Baby's daddy: Canadian model boyfriend Gabriel Aubry

Defining Maternity Moment: It just goes to show that looks aren't everything: Despite being one of the most gorgeous women on the planet, Berry could not find a good man, divorcing baseball player David Justice and then R&B crooner Eric Benet. She finally got lucky with superhottie and reportedly nice guy Aubry. With two such uber-stunning parents, this baby's hit the genetic jackpot -- and may even give Shiloh a run for her money.

Christina Aguilera
Due date: January

Best known for: Possessing killer pipes, and going from sexed-up to old-school on her latest album, Back to Basics

Baby's daddy: Music exec husband Jordan Bratman

Defining Maternity Moment: Privacy, apparently, is what a girl wants. Aguilera has still never officially confirmed her preggo status, but she has pointed out her bump with a big smile on stage, and Paris Hilton recently forced her out of the pg-closet by calling her "the most beautiful pregnant woman in the world."

Nicole Richie
Due date: January

Best known for: Starring in The Simple Life -- and being very very skinny

Baby's daddy: Good Charlotte rocker Joel Madden

Defining Maternity Moment: And you thought everyone knew about you well before the 12-week safe-to-tell mark! Buzz that the itsy-bitsy Richie was preggers started when she was just 10 weeks along. She used all manner of diversions -- pillows, flowy clothes, huge designer purses -- to hide her bump, but when she confirmed the pregnancy at almost four months, we all already knew.

Salma Hayek
Due date: Daughter Valentina Paloma was born September 22.

Best known for: Playing Frida Kahlo in the film Frida and being a producer and regular guest star of the surprise hit, Ugly Betty

Baby's daddy: Businessman fiance Francois-Henri Pinault

Defining Maternity Moment: Pulling off a Katie Holmes-style shocker: Hayek announced her pregnancy and top secret engagement (no one even knew they were dating!) at the same time.
