Justin Timberlake to propose to Jessica Biel?

Justin Timberlake is reportedly set to propose to girlfriend Jessica Biel.

A source close to Justin told the Sun that the singer is “thinking about marriage and kids” with the I Now Pronounce You Chuck and Larry star: “For the first time in his life he is feeling settled and has definitely decided to pop the question to Jessica.

“He is so happy with her. They spent quite a bit of time apart recently when Justin was working with Madonna [last year] and that made him certain Jessica was the person he wanted to spend the rest of his life with.”

The source added that Justin is already thinking wedding venues and is thinking of going for Mustique, a private island in the Caribbean: “Although Justin has lived his whole life in the public eye, he feels his wedding is the one day that should remain private.

“To get all his close friends and family to Mustique will cost a fortune. But he can’t put a price on how he feels about Jessica.”

Justin started dating Jessica in January 2007, shortly after ending a four year relationship with Cameron Diaz.

Justin appeared on the The Ellen DeGeneres show last week just after Ellen had announced that she would be marrying long term girlfriend Portia De Rossi but laughed off the suggestion that the two couples should have a double wedding: “No… but I’ll sing at your wedding.”

“You should have an original wedding song; I think it’s only fitting.

“[Write down] everything you want to say to Portia and everything you [Portia] wanna say to Ellen… and I’ll put it to music and it’ll be amazing.”
