The Vamps take us on a 1990s nostalgia trip!

Yes, you DID hear that right! Brad, Connor, James & Tristan covered '90s boyband Hanson's MASSIVE track 'Mmm Bop!'. Here's hoping they bring some surprises like that to the Jingle Bell Ball!

Lady Gaga Shocked Us All With New 'ARTPOP' Promo Film By Haus Of Gaga

"My pain is exploding in electronic music," Lady Gaga explains in a voice-over to begin the video. "It's heavy but after I listen to it I feel happy again. I feel lighter". Some people were shocked by Mother Monster's wigs and dresses, but we just loved it!

And in a COMPLETE contrast, melts our hearts with a Muppets Holiday Spectacular!

It wouldn't be the festive period without our favourite pop star mingling with our favourite fuzzy puppets! We're not gonna lie, Winter 2013 included a lot of time spent under a duvet watching the full show on repeat!

Speaking of fuzzy puppets, Ed Sheeran & Macklemore got us SO excited when they told us how to get, how to get to Sesame Street!

The special behind-the-scenes video was a sneak peek of an upcoming episode - apparently Elmo even called Ed to get him on the show (which is the CUTEST mental image ever!)
