(showbizspy.com) - Justin Timberlake has proposed to girlfriend Jessica Biel, according to British tabloid reports
The pair were in Rome this week when the SexyBack hitmaker popped the question on the last night of their break, reports the Sunday People.
A source tells the publication, "Justin 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.
"He has grown up a lot in the last couple of years and has decided it is time to settle down."
The couple -- who have been dating for nearly two years -- had jetted to Italy for the wedding of actress Beverley Mitchell.
Jessica -- who played Beverley's sister in TV drama 7th Heaven -- was one of seven bridesmaids.
Justin has previously dated Cameron Diaz and Britney Spears.
