Capital FM's Jingle Bell Ball took place in London's O2 Arena this weekend, last night and Saturday night, and our leaping leprechauns (honestly, if they keep doing that in tight pants they're going to render themselves infertile) were asked to perform at both events. According to The Sun, they sent their dad around the dressing rooms to gather autographs from their fellow "artists", which included Lady GaGa; Alesha Dixonin some undersized Cinders gear (preparing for the inevitable so soon?); Shakira looking uncharacteristically trashy (the hair tops it off); and fellow twins, The Veronicas (who've both gone brunette... confusing)

As usual, there were those who looked the part - Alexandra Burke, Lisa Snowden, Johnny Vaughn, Ne-Yoand Pixie Lott for example - along with the usual tragedies, in this case The Saturdays who clearly consider themselves to be as talented as the Pussycat Dolls... Flo Rida looked just as classy, as did The Sugababes Part III  in their cut and shut efforts, while someone called Jesse Malakouti chose to epitomise the term try-hard. Jesse - the hair didn't work for Sarah Harding the first time round. Oh, and your shorts - if you must wear them over tights - should always cover the control top pants part... At least she didn't pull a Shingai Shoniwa and have a hole in the gusset. As for La Roux; there's little point in commenting anymore.

Finally, The Back Street Boys tried to go with effortlessly "cool", but then Nick pulled a Jedward 'cause, well, he just couldn't help himself.
