Who's J. Lo's 'Papi'?

You've got to wonder about the American Idol hosts' personal lives, especially when one of them is the one and only Jenny from the Block. Thursday, judge Jennifer Lopez will perform "I Luh Ya Papi" on the American Idol stage... so is Casper Smart the sung-about "papi?" Is Jennifer Lopez still even dating Casper Smart?

It looks like the "papi" she "luhs" still is Smart, the dancer and choreographer she's been with since 2011. The two were spotted together on Wednesday grabbing a laid-back dinner, so let's assume that they're still together. She also donned quite the red sweatsuit ensemble; the word is still out if anybody other than J. Lo can pull off that kinda thing.

But we shouldn't forget that she's loved a lot of other papis before, which may explain why she's hesitant to wed Smart. She herself has said that she's unsure if she'll wed again. She's had three failed marriages, after all — Marc Anthony, who left her devastated after the split, who's also the father of her two kids, Max and Emme; Criss Judd, a back up dancer she married in 2001; and waiter Ojani Noa, who was her first husband back in 1997.

And please, of course you remember her high profile romances with P. Diddy (who was Puff Daddy then — do you feel old yet?), and Ben Affleck (Bennifer, Gigli, eek — we know how that story goes).

So, yes. Jasper are still a happy couple. Way to be, guys. Way. To. Be.
