Exclusive: Tiffani Thiessen Pregnant!

After years of trying Saved By The Bell cutie Tiffani Thiessen, 34, is finally going to be a mom.

A source tells Star that the actress has been staying low key with the news because she's in the early stages of her first pregnancy. "She and her husband are over the moon at the thought of becoming parents."

"Tiffani wanted a baby so badly," the source adds. "She had been seen going to a fertility center for treatments in Los Angeles to help her conceive."

The former Beverly Hills, 90210 star has been married to Brady Smith since July 2005.
