There is an unconfirmed report that singer and actor Justin Timberlake proposed to his girlfriend Jessica Biel at a luxury resort in Wyoming last December 19.

According to sources, the two were spending the holidays at a five star skiing resort in Jackson called the Amangani where the singer is believed to get down on his one knee and asked the 29-year-old actress to marry him.

However, an art gallery in Jackson picked up the news and took to Twitter to post about the couple's engagement. "Word on the street is that Justin Timberlake proposed to Jessica Biel at the Amangani last night," the art gallery stated.

Justin and Jessica have been together for four years. Last year, the two were not seen together and break up rumors were confirmed last March. However, Mirror reported that the "Friends With Benefits" star was seen visiting Biel on set in Toronto in Canada over the summer.

The pair was then spotted spending time together in New York a few times in August, and by September, it seems that the pair is clearly back together. However, none of the representatives of the two confirmed or denied the reports.

Both Timberlake and Biel were linked to other people during their time apart. He was linked to his "Friends With Benefits" co-star, Mila Kunis, as well as recently divorced actress Scarlett Johansson, while Biel was reported to have dated Bradley Cooper and Gerard Butler.

Celebrity columnist Perez Hilton said that he was not convinced of this news.

The blogger wrote, "Hermmm...we're not really sure we believe this one... First of all, we highly doubt JT would actually do this not even a week after Britney (Spears) got her rock (a reference to Timberlake-Spears' much-talked-about relationship). It's not smart. Even if he had it planned, we would think he'd postpone it."

"Second, at a ski resort in Wyoming??? Nahh... But! If it is true (and the reps' denials have yet to flood), then congrats! But we're not sold yet," he concluded.

Justin's ex-girlfriend, Britney Spears, also got engaged last week to her boyfriend Jason Trawick.
