Bruce Willis and wife Emma Heming are expecting their second child together, sources confirmed earlier today.

Speculation over Emma's possible pregnancy have began to circulate over the previous weekend, when the celebrity couple was spotted visiting a Los Angeles neighborhood farmer's market with daughter Mabel last Sunday. The couple was enjoying a family day outing with their only daughter and witnesses reportedly saw Emma visibly showing and looking more round as of late.

Emma appeared to be several months pregnant when she was spotted during the outing, as her baby bump seemed to be protuding through her clothing. The supermodel did not seem to be hiding her bump but it was only earlier today that rumors of her pregnancy had been confirmed.

Willis and supermodel wife Heming's first daughter Mabel is 20 months old. Willis has four children in all, including daughters Rumer, 25, Scout, 22, and Tllulah, 19, from his marriage with ex-wife Demi Moore.

The Die Hard star recently gushed on how much he enjoys being a father and all the perks that come with it.

"I've never been as happy as I am now!" the actor told German magazine Bild in an interview. "I feel like a caveman protecting his family, living for his family. I have four daughters, I get up at seven am when our baby wakes up. My family has become the focus of my life and the entire meaning of it.

Wilis continued to share how fulfilling being a father feels and described fatherhood as "the most wonderful task."

Willis, 58, has made his name in the movie industry with films such as the Die Hard series and Red. 

Bruce Willis and Emma Heming got married last March 2009 in the Carribbean Turks and Caicos Islands in a private ceremony. No other further details were disclosed regarding Emma's pregnancy.
