Secret Weekend Wedding for Jessica Biel and Justin Timberlake?

Noted gossip columnist Janet Charlton claims an insider spilled the bouquet on the secret wedding ceremony of on-again, off-again partners Jessica Biel and Justin Timberlake, which supposedly took place this Saturday in Jackson Hole, Wyoming.

"They pulled a fast one on everybody," Charlton wrote on her blog. "They are in the middle of their ceremony at a very fancy private estate and members of the wedding party are staying at the Four Seasons Hotel there."

The wedding rumors have been simmering for months, despite a recent denial from Biel that wedding plans were not a priority.

Adding some credibility to the claim, wedding cake maker to the stars Sylvia Weinstock tweeted on Saturday that she was in Jackson Hole, though would not say why.

Lainey Gossip, meanwhile, says Splash News has photos of Biel in Puerto Rico over the weekend, noting the Timberlake is shooting a film there.

Biel and Timberlake have been dating since 2007, though they separated for several months last year. After the couple reunited last fall, Timberlake proposed to Biel in the mountains of Jackson, Wyoming.

So far no word from either of the actors' reps.
