Jessica Alba seeks advice on sex during pregnancy - video

Jessica Alba has shared her concerns about sex during pregnancy.

Alba revealed that she is expecting her second child with her husband Cash Warren last February. The two already have a 3-year-old daughter named Honor Marie.

While appearing on The Tonight Show last night, the Machete star took the chance to ask fellow guest, sex educator Sue Johanson, about whether it is safe to have sex while pregnant.

"As someone who's in the later stage of pregnancy, is there any way to harm the baby during intercourse?" Alba asked Johanson.

"Absolutely not. That baby is in there and that baby ain't going nowhere until it's ready," Johanson answered.

"That uterus wall is just like that," she continued, knocking on the arm of her chair.

Alba celebrated her second pregnancy with a baby shower over the weekend, later thanking friends and family for the party via Twitter.

Alba can next be seen in Spy Kids: All the Time in the World in 4D.
