Justin Timberlake and Jessica Biel have sparked rumours they have wed in secret.

Singer Justin and actress Jessica reportedly got married over the weekend in the ski resort of Jackson Hole in Wyoming.

Justin proposed to Jessica at the same destination in December last year and reports say this was also their choice for the nuptials.

The top secret ceremony apparently almost went unnoticed by fans and paparazzi.

Celebrity wedding cake designer Sylvia Weinstock reportedly revealed she was in Jackson Hole, sparking speculation the couple could be getting hitched.

"Justin and Jessica married in the Wyoming resort town," an insider reported to the Examiner.com. "The wedding goers holed up at the deluxe Four Seasons Hotel while the nuptials were said to take place at an upscale, private estate."

Total Recall star Jessica recently said she had no plans for an imminent wedding ceremony. It is reported this could have been a ploy to throw people from the fact the nuptials were planned for Saturday.

"They pulled a fast one!" gossip columnist Janet Charlton claimed at the weekend. "They are in the middle of their ceremony at a very fancy private estate."
