Jennifer Lopez Shoots Down Engagement Rumors

Jennifer Lopez is a really big fan of boyfriend Casper Smart. She believes he's a good egg.

But that doesn't mean the singer/American Idol judge is ready to walk down the aisle for a fourth time, regardless of any bling that may be on her finger. After all, remember the refrain from a certain 2002 J. Lo single?

"Rumors!!!" Lopez wrote on her website Friday of chatter that she and Smart were engaged. "Don't be fooled by the rocks that I got."

Lopez and Smart got together last fall, and their relationship has only heated up since, both personally and professionally.

Smart, in fact, will anchor an upcoming reality show that follows around Lopez and her backup dancers during their world tour.
