Justin Timberlake is thought to have proposed to on/off girlfriend Jessica Biel, according to Us Weekly magazine.
The Stateside publication claims that JT popped the question to Biel just before Christmas in a romantic winter setting, with pals of the former NSYNC star stating that he's "never been happier."
Despite previously being linked to his Friends With Benefits co-star Mila Kunis, Timberlake has apparently decided to settle down with his girlfriend of four and a half years, with friends claiming he "knew it was the right time to propose."
The Like I Love You singer is said to have asked Jessica to be his wife during a pre-festive break to Jackson, Wyoming, getting down on one knee in the mountains.
A source told the mag: "Justin knows how much she loves snowboarding and the mountains, so it was the perfect place."
After splitting for three months last year, the insider claims marriage was on the cards after their reconciliation, stating: "This was the basis for getting back together. When they reunited they had a conversation about taking the next step."
Justin and the New Year's Eve actress allegedly celebrated their engagement with friends and family at Timberlake's home in Big Sky, Montana.
There is still no official word from either Justin or Jessica's camp regarding the rumours, but keep in MTV.co.uk for more on this story...
