Busy Philipps is expecting her second child!

Cougar Town's Busy Philipps (aka Michelle Williams' bestie), 33, is pregnant!

Yes, her rep has confirmed it: Busy and her husband, Marc Silverstein, are expecting their second child together — they already have a four-year-old daughter, Birdie Leigh.

Busy announced the big news on Twitter yesterday. "So this happened...," she tweeted, along with a photo of her positive Clearblue pregnancy test (wild!).

Congrats to the family!

Off to add Busy to our Who's Pregnant in Hollywood gallery!

Love!
