Lady Gaga has become the latest in a long line of celebrities to have their own Muppets special, when she teamed up with Kermit and the lads on Lady Gga & The Muppets' Holiday Spectacular. 

Gaga sang a duet of 'Gypsy' with Kermit the Frog, as well as a rendition of this writer's favourite Christmas song 'Baby, It's Cold Outside' with Joseph Gordon Levitt, both of which you can see below.

It appears, though, that the famously grumpy duo of Statler and Waldorf were none too impressed with the performances, Tweeting on the official Muppets' account "There's nothing like a classic holiday song. And that was nothing like a classic holiday song."

Also featured on the holiday special were Gaga's chum Elton John, Kristen Bell and RuPaul.

Gaga is no stranger to The Muppets. A self-confessed superfan, she has appeared on stage with them in the past and has also bagged a small role in the 2014 feature film Muppets Most Wanted.
