Justin Timberlake and Jessica Biel are finally engaged.

The singer-turned-actor popped the question while they were on vacation in Wyoming, according to an Us Weekly report.

"Justin knows how much she loves snowboarding and the mountains, so it was the perfect place," a source told the magazine.

This will be the first marriage for both of them.

Biel came to fame on the television family drama "7^th Heaven." Her role was greatly diminished after she posed nude for a magazine at the age of 17. She has since moved on to film work, with roles in action films such as "Stealth," comedies such as "I Now Pronounce You Chuck and Larry," and dramas such as "The Illusionist."

Timberlake, the former lead singer of the now-defunct group N'Sync, has been linked to several Hollywood ladies, but he was in longer, more steady relationships with Cameron Diaz after famously being linked to Britney Spears. The former Mouseketeers began dating in 1999 and stayed together during the heights of their respective musical careers before breaking up in 2002. Timberlake and Diaz split in January 2007, but reportedly remained friends and eventually became costars in the 2011 film "Bad Teacher."

Biel and Timberlake reportedly started dating shortly after he and Diaz broke up. They seemed like a steady, low-key couple, but split in early 2011.  

But absence made the heart grow fonder, apparently. They got back together later in the year and Timberlake reportedly proposed in December.
