Rumours are rife that the pair married in a top secret ceremony while on holiday in the ski resort of Jackson Hole, Wyoming.
The Trousersnake, 31, and Total Recall star Biel, 30, got engaged at the resort last Christmas.
Wedding cake designer Sylvia Weinstock is said to have fessed up to being at Jackson Hole, adding fuel to the fire.
Web gossip columnist Janet Charlton wrote at the weekend: “They pulled a fast one! They are in the middle of their ceremony at a very fancy private estate.”
An ‘insider’ also told Examiner.com: “Justin and Jessica married in the Wyoming resort town. The wedding goers holed up at the deluxe Four Seasons Hotel while the nuptials were said to take place at an upscale, private estate.”
However, there has so far been no confirmation from either camp. The lack of anything approaching evidence also makes us a little dubious about this particular Hollywood rumour.
