London Actress Julia Roberts says she has the perfect wedding present in mind for newly-engaged Angelina Jolie and Brad Pitt. The Pretty Woman star, who has her hands full with her own three children, has offered to babysit the couples six children, reported Femalefirst. "People are starting to ask me and put pressure on me. Babysitting. Yeah, that's good. It's an exciting news. It's always nice when you're ready to hitch your wagon for eternity to somebody," she said. The stars of 2005 film Mr. & Mrs. Smith announced their engagement earlier this month. They are raising six children together, including Maddox, Pax, Zahara, Shiloh, and twins Knox and Vivienne.
