Reese Witherspoon Baby Bump: Pregnant Actress Hits The Beach (PHOTO)

Well, there's no denying it now. Reese Witherspoon hasn't announced her third pregnancy, but her baby bump was on full display as she enjoyed some beach time this week.

Witherspoon, along with her husband, Jim Toth, and her two children, Ava and Deacon, hit the beach in Costa Rica on April 4 while enjoying a family vacation. Witherspoon was spotted wearing a one-piece bathing suit while having some fun in the sun.

Rumors started swirling earlier this year that the actress is pregnant with her first child with Toth, which whom she tied the knot last year. Sources confirmed the rumors to Us Weekly in March; however an official announcement from the couple hasn't been made, nor is it expected.
