Everybody remembers their best kiss, but that doesn't mean everyone wants to share that memory with strangers!
"Do you remember your best kiss ever?" ET's Nischelle Turner asked J. Lo on the blue carpet outside the MTV Movie Awards.
"Ever?" the American Idol judge asked, shyly. "Oh God! I've had a few good ones."
But that was the most the 45-year-old "On the Floor" singer wanted to share.
Currently, it's been rumored that Jennifer and her ex-flame Casper Smart have been rekindling their former romance. Recently Smart even posted an Instagram video of the pair taking a bike ride in Santa Monica. Check out the video below for a look at their possible romance.
