Beverley Mitchell pregnant with first child

Actress Beverley Mitchell has revealed that she is pregnant with her first child.

Mitchell, 31, who played Lucy Camden on the TV series "7th Heaven," told People that she and husband Michael Cameron, 32, will welcome a baby in April.

She told the magazine she discovered she was pregnant after her sense of smell perked up: "My sense of smell was off the charts, to the point where I could smell a kid's dirty diaper from the other side of a restaurant."

Still, she added, "I was like, 'No, it can't be that.' I took seven pregnancy tests. I went to the doctor and had two more tests and they were like, 'Bev, usually when the first one comes out positive, the rest of them will all say the same thing.'"

Mitchell, who also appears on "The Secret Life of the American Teenager," married Cameron in Italy in 2008. The couple recently returned to Italy to mark their anniversary and to attend the wedding of Mitchell's friend and "7th Heaven" co-star Jessica Biel to Justin Timberlake.

"Jess was one of the first to know [the baby news]. I started crying," Mitchell told People. "It was really exciting to share that with Auntie Jess."
