Pop sensations settled down for interviews as they prepared for their Jingle Ball concert.
As usual, the Y100 Jingle Ball was a pop explosion with some of 2014's biggest chart sensations giving it their all on this year's stage in Miami, Florida. Among which we saw Ariana Grande, Pharrell and Iggy Azalea - but what did they get up to backstage?

'Miami's #1 Hit Music Station' Y100 hosted the perfect pre-Christmas concert on December 21st 2014 at the BB&T Center with this year seeing ultra sultry performances from the likes of Ariana Grande and Jessie J - who looked like serious besties as they hung out backstage, ever since they collaborated with Nicki Minaj on J's number one 'Bang Bang' earlier this year.

Both J and Grande enjoyed the unseasonal Miami rays as they flashes some flesh in equally skimpy ensembles; J in a sheer black number and Grande in a black corsetted bodysuit with knee high boots. Looking a bit more comfortable but no less sexy backstage was Iggy Azalea in a burgundy sweater and matching leather pants as she signed some Jingle Ball 2014 posters, though she was sure to change for her stage performance - making us green with envy as she bared her midriff in an emerald crop top and more skin-tight pants.

Several stars took to the backstage lounge to give interviews with Nina and Mack from Y100, Pharrell losing his famously oversized hat in favour of a candyfloss pink one of a more sensible size, while 'All About That Bass' hitmaker Meghan Trainor echoed him with a similar coloured jacket.

More stars to hit the stage at the show were 'Rude' singers MAGIC!, emerging British boyband Rixton, California starlet Becky G, Kiesza who had a hit with 'Hideaway' earlier this year, online sensation Shawn Mendes, recent Billboard cover guy Jason Derulo, the newly solo Nick Jonas, Iggy Azalea's 'Fancy' collaborator Charli XCX and Bronx singer and producer Prince Royce.

The biggest backstage attraction was by far, however, Jiff the Pomeranian, who donned a black and white shirt and dog tag, and stole Jessie J's heart with its minuscule Santa hat! Too cute.
