Heartthrob RnB star Justin Timberlake has proposed to girlfriend Jessica Biel, according to a source.

The former N*Sync star is said to have popped the question during a holiday in Rome last week, and hope to have the big day in the next 18-months.

The source told the Sunday People: “He is besotted with Jessica and wants to make an honest woman of her… He planned to propose in Rome because it is such a romantic city. Jessica is over the moon and looking forward to a huge wedding. She can’t wait.”

So Audio just wonders what Britney Spears will have to say on this!?
