IS Jennifer Lopez's engage??

Here we go again—another Jennifer Lopez engagement rumor is on full throttle!

The latest round of speculation that J.Lo, 43, and beau Casper Smart, 25, are planning to marry started the other day at Paris Fashion Week when Lopez wore a massive ring of bling to the Chanel show.

Lopez sat in the front row at Chanel with daughter Emme and Smart. It also appears that she wore the same ring to the Valentino show later that day
