Anyone else think Nicola Roberts is looking a bit peeky here? I know she doesn't like smiling, which is very sophisticated, but she's looking a wee bit more maladies ridden than usual.

Perhaps she was just having an off day. Or perhaps she, like Gillian Anderson, realised the guest list largely comprised of X Factor contestants.

Nicola, if Christian Louboutin himself can rustle up a smile despite the company, you can too. Then again, he's not got the vocally talented Little Mix snapping at his heels.
