So apparently, rumors have been rampant for years that Jennifer Lopez & Mariah Carey had beef.  J-Lo sat for a fun interview on "Watch What Happens Live" & addressed that rumor.  What surprised me was that she claims she & Mariah have never met.  Wait, wha?!  You're both from New York, you're both megastars for years...but you've never met?!  Odd.  Anyway, watch below to hear what J-Lo had to say about MiMi, her fashion influence over ex-Ben Affleck and whether actors, dancers or singers are better in bed...
