Jessica Biel and Justin Timberlake are rumoured to have tied the knot in secret.
The engaged couple, who have been dating on and off since 2007, have been tight-lipped about their wedding plans, with Jessica even saying recently that they hadn't started planning their big day.
But the internet is now buzzing with marriage rumours after gossip website JanetCharlton.com reported that they "pulled a fast one on everybody" and got hitched at the weekend.
Jessica and Justin, who rarely speak publicly about their romance, apparently exchanged vows at a private estate in Jackson Hole, Wyoming, the place where Justin is thought to have popped the question late last year.
The Sun reports that wedding cake designer Sylvia Weinstock also revealed that she was in Jackson Hole, adding more weight to the rumours.
Earlier this month Total Recall star Jessica, 30, insisted she wasn't rushing to plan her wedding with Justin, 31, because she was enjoying being engaged so much.
She said: "You're in this romantic, ahhhhh, breathless moment that I'm just trying to extend as long as possible."
