Justin Timberlake and Jessica Biel got married in a secret ceremony on a private estate over the weekend, according to a report.

The Total Recall star and the SexyBack singer are said to have wed in Jackson Hole, Wyoming, where they got engaged in December 2011, according Contactmusic.com. Hollywood gossip columnist Janet Charlton said: ''They pulled a fast one!''

Despite their attempt to keep the big day a secret, wedding cake designer Sylvia Weinstock added fuel to speculation by revealing she was in Jackson Hole at the weekend. Taking to her Twitter page, Weinstock wrote: ''America is a beautiful country Jackson hole a marvel (sic)''

Jessica recently stated she hasn't had time to plan her wedding, but admitted she was worried about having a bridal freak out on her wedding day.

She said: ''It's very exciting but it's hard to find the time for it! But it's a good moment just to enjoy it.

''I have no idea of what I want. I am one of those people who are not very detailed orientated. I don't feel like I'm one of those people who is like, 'This has to be done this way.' I'm more of a big idea person. I will probably give an idea and let it be created.

''I feel like most of my friends, bless them, always go through some sort of something - one day of 'bridezilla'. Maybe it's just part of the experience.''
