Wyclef Jean out and about in Sydney. Australia - 24.04.08.

The actress gave birth to son Knox Leon and daughter Vivienne Marcheline by Caesarian section at the Fondation Lenval hospital in France - and Jean is now hoping to lend the new parents a helping hand.

He tells People.com, "I'm willing to babysit for them!"

The hip-hop singer's three-year-old adopted daughter, also named Angelina, is already friends with Jolie's kids Maddox, Pax, Zahara and Shiloh - and he's convinced Jolie and Pitt will be able to cope with their expanded brood.

He adds, "They will do well. I have a lot of well wishes for them."
