'X Factor': Rylan Clark Celebrates His Birthday With Halloween-Themed Night Out (PICS)

The 'X Factor' contestants had a fright last night (no, they didn't walk in on Louis Walsh getting changed in his dressing room) as they all tried to outspook each other with their best Halloween costumes on Rylan Clark's birthday night out.

As the flamboyant contestant celebrated his 24th, he flashed the flesh in a Vampire/American footballer mash up, while best pal and fellow hellraiser Lucy Spraggan came as a giant pumpkin.

Rylan was up to his usual antics, climbing on a motorbike and snogging MK1's Charlie Rundle, but things were much tamer in comparison to Rylan and Lucy's infamous drinking session last week, which saw them chucked out of the 'X Factor' hotel.

Despite newspaper reports that Tulisa had banned her contestants from partying with Rylan, she turned up to join in the fun at London's Mahiki club dressed as a sexy vampire.

She was joined by her PA Gareth Varey and star of her recent 'Sight Of You' video, Jody Lantham, along with some other pals.

Fellow judge Nicole Scherzinger was also spotted arriving, and kept her PVC costume hidden under a rubber coat and fishnet stockings. Kinky.

The other contestants got in the spirit too, with District 3 dressing as devils, Union J as zombie nurses, Chris Maloney coming as a warewolf, Kye Sones as Frankenstein and James Arthur as Dracula.

Jahmene Douglas joined the gang, but didn't dress up, as axed contestants MK1, Melanie Masson and Jake Quickenden also met up with their ex-co-stars.

But poor Ella Henderson was left out, as at just 16, she's too young to hit the town.

Looks like she missed a quiet night...
