Jennifer Lopez is facing a new round of wedding rumours after she was spotted sporting a huge diamond on her ring finger.

The three-times wed singer/actress began dating backing dancer Casper Smart last summer (11) after she split from husband Marc Anthony, and she sparked speculation they were engaged in June (12) after the superstar was seen wearing a new ring.

Lopez quickly shot down the rumours at the time, but sent gossips into a spin once again earlier this week (begs01Oct12) while out and about in France for Paris Fashion Week with a giant sparkler on her engagement finger.
