Not in order... 1. It's a wonderful life 2. Scrooged 3. Love actually 4. Family man 5. Elf (sic)."

It has also now been confirmed that the beauty will perform at the 2014 GRAMMY Awards and she will duet with fun.'s Nate Ruess on their collaborative hit single, 'Just Give Me A Reason'. The executive producer of the GRAMMYs, Ken Ehrlich, said in a statement:

"In the past four years, both Pink and Fun. have given us some of the most memorable Grammy performances, with 'Glitter In The Air' and 'Carry On'. It was an easy and natural ask to have them perform on this year's show because their collaboration is nominated, and with these two incredibly strong voice - arguably two of the most signature voices in pop and rock - there's no doubt that viewers will be treated to a very special Grammy moment."
