Jennifer Lopez has dismissed reports she's secretly wed her younger lover Casper Smart.
 
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 a year for the next decade.
 
But Lopez - who split from her third husband, salsa singer Marc Anthony, last summer - has brushed off the new tabloid claims.
 
In a Twitter post on Thursday, she writes, "I keep seeing something about getting married. Surprise, surprise "they" are wrong...AGAIN. #boredtweet".
 
It's the second time Lopez has had to deny rumors 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 page had been hacked.
