Jimmy Fallon is so popular as the new host of "The Tonight Show" that sometimes celebrities aren't even being interviewed, they just stop by to do something goofy. Such is the case with "American Idol" judge Jennifer Lopez, who has been making headlines recently for both her split from Casper Smart and pulling out of performing at the 2014 World Cup opening ceremony.

But this "Tonight Show" appearance was all fun, as J-Lo and Fallon put on their best mop-top wigs and tightest white pants for a "Tight Pants" dance-off. But it's not just a dance contest, there's a whole song that goes along with it, and then J-Lo calls Fallon a "little b****" and threatens to cut him because her pants are the tightest. Hee.

There has been no official word about Lopez coming back for "American Idol" next year. Do you hope she returns?
