Rebecca Romijin Congratulates Ana Ortiz on Pregnancy

New mom of twin girls, Rebecca Romijn, is over the moon about co-star and pal Ana Ortiz's pregnancy.

Rebecca tells OK!, "I'm so happy for Ana. She is going to be such an amazing and fun mom. And if she has a boy, he's already got two dates for the prom. And if she has a girl, she's about to get a TON of hand-me-downs!"

Romijin, who's married to Jerry O'Connell, gave birth to twin girls Dolly Rebecca Rose and Charlie Tamara Tulip on Dec. 28.
