When Jennifer Lopez attended the Chanel Show in Paris on Tuesday, she was snapped wearing a massive diamond sparkler on her left ring finger, so we have to ask whether beau Casper Smart proposed to her!

We got a peek at the ring when J. Lo stepped out of her car and reached down to grab daughter Emme's hand, and this is definitely one we haven't seen the 43-year-old singer/actress wearing before. J. Lo's manager had no comment on a possible engagement, and her publicist has yet to respond to our inquiries about the ring.

Lopez has been married three times before (she was married to Ojani Noa from 1997 to 1998, then to dancer Cris Judd from 2001 to 2003, and then to singer Marc Anthony from 2004-2011), and she also also engaged to Ben Affleck, but the couple called things off in 2004. Think she's ready to tie the knot for a fourth time?
