Justin Timberlake and Jessica Biel are reportedly engaged, if you believe the rumors that have been swirling about the on-again-off-again power couple.

On Monday, Tayloe Piggott Gallery in Jackson, Wyo. tweeted a Facebook post alluding to the betrothment. The message says Timberlake got down on one knee at Amangani, a luxury resort in Jackson Hole, but offers no other information about the rumor.

The post reads: "Word on the street is that Justin Timberlake proposed to Jessica Biel at the Amangani last night...we're picking out post-engagement presents for them just in case they come in! Trying to play it cool..."

However, the Wyoming gallery isn't the only source that's supporting the rumor. International Business Times reports that New York City publicist Kyle Schaffler also tweeted about news on Tuesday. His Twitter page is currently protected, but IBT says he wrote: "Hehe, I love that NO media outlets know about the Justin Timberlake and Jessica Biel engagement. Benefits of working in PR."

After splitting in March 2011, Timberlake and Biel reconciled in October when the pop star showed up to the 'In Time' premiere after-party in Los Angeles with the 'New Year's Eve' actress. Thus far, neither JT nor JB have confirmed or denied the reports.
