Fairytale Of New York The Pogues feat. Kirsty Maccoll
Ke$ha's not even nominated for an award - this year - but she's dropped in on the BRIT Awards to see, amongst others, Florence and The Machine.
Check out Rich and Kat's BRITs studio, which comes complete with on tap champagne and more sweets than Woolworths. (Before they went bustm, which we're still upset about to be honest.)
