You hate to see a legendary couple argue, but Kermit the Frog and Miss Piggy established themselves as the new Burton and Taylor when we interviewed them at the "Muppets Most Wanted" junket. A shame they couldn't be maintain professionalism like their castmates Tina Fey, Ricky Gervais, Ty Burrell, and the nefarious frog czar Constantine (interviews coming soon!), but I'm hoping they'll settle their differences with a new duet of "Rainbow Connection" or at least a Broadway revival of "Private Lives." 

"Muppets Most Wanted" opens March 21.
