Washington: Jennifer Lopez has dismissed reports claiming that she married toyboy Casper Smart in a secret ceremony.

The superstar found a photo of herself on the cover of this week’s Star magazine alongside the headline, “J.Lo Married in Mexico!”

The accompanying article alleges the singer-actress married dancer Smart in a low-key ceremony onboard a yacht - with no guests in attendance.

The story also suggested Lopez had signed a prenuptial agreement promising her new husband 1 million dollars a year for the next decade.

However, Lopez - who split from her third husband, salsa singer Marc Anthony, last summer - has brushed off the new tabloid claims.

“I keep seeing something about getting married. Surprise, surprise “they” are wrong...Again. #boredtweet,” Contactmusic quoted her as tweeting.

It’ the second time the singer has had to deny rumours she's heading down the aisle again - last week, she shut down false allegations claiming she had asked fashion designer Roberto Cavalli to create a new wedding dress, insisting the style guru’s Twitter.com page had been hacked.
