Actress Busy Philipps is set to be a mom again.

The Cougar Town star and her husband Marc Silverstein are expecting their second child next year.

Posting an image of a positive pregnancy test on her Twitter.com account on Monday, Philipps wrote, "So this happened..."

And her representative, Carrie Byalick, tells Life & Style magazine, "I can confirm she is pregnant."

The couple is already parents to four-year-old daughter Birdie Leigh.
