Jennifer Lopez's representative dismisses latest engagement reports

A representative for Jennifer Lopez has brushed off speculation the superstar is engaged to her dancer beau Casper Smart.

The three-times wed On The Floor hitmaker sparked a new round of rumors suggesting she was heading to the altar once again after she was spotted sporting a large diamond on her ring finger while in Paris, France earlier this week (begs01Oct12).

However, Lopez's spokesperson has now dismissed the reports, telling Eonline.com, "Jennifer is not engaged."

It's the second time in four months Lopez and Smart have faced wedding claims - the singer/actress had to shoot down allegations she was planning her fourth wedding in June (12) after she was seen wearing another sparkler on her ring finger.

Lopez split from her third husband, Marc Anthony, last year (11).
