Jennifer Lopez's representative has played down fresh rumours the superstar is planning a secret Christmas wedding to her boyfriend Casper Smart after they were photographed shopping for diamond rings in Australia.

The couple, which began dating last year (11) following Lopez's split from husband Marc Anthony, was snapped browsing for sparklers at top jewellery store Tiffany & Co. in Perth on Thursday (06Dec12), prompting speculation the singer/actress was set to head to the altar for the fourth time.

However, the On the Floor hitmaker's spokesperson insists that is not the case, telling the New York Daily News, "Jennifer and Beau (Smart) were not shopping for wedding rings."

Lopez, who is currently on tour Down Under, and her dancer lover have been dogged by wedding claims since she was spotted wearing a diamond on her ring finger back in June (12). They denied talk of an engagement at the time, and brushed off fresh speculation in October (12), after the beauty sported a large jewel on the same finger while in Paris, France.

The lovely Latina was previously married to waiter Ojani Noa and dancer Cris Judd, while she has also enjoyed romances with rap mogul Sean 'Diddy' Combs and actor/director Ben Affleck.
