Elizabeth Berkley is pregnant!

Yes, the former Saved by the Bell star, and author of the teen girl's guide, Ask Elizabeth: Real Answers to Everything You Secretly Wanted to Ask about Love, Friends, Your Body and Life in General, is pregnant!

Elizabeth, 39, was photo'd with a sizeable second-trimester belly just yesterday, and later that day announced on Twitter that she and handsome hubby Greg Lauren (left) are, indeed, expecting their first child: "In life there are moments you cherish forever and this is one of them. Greg and I are so excited to be expecting our 1st child this summer."

Congrats! Love! xo Haley-O
