Does Diana Vickers think she’s Lady Gaga?

We hardly recognised Diana Vickers when she performed at G-A-Y last night, but we can’t help but think we’ve seen her look somewhere before recently…

No, it’s not Lady Gaga, it’s former X Factor contestant Diana Vickers, sporting long straight (and brushed, we’re so happy) hair, a leopard print leotard, high heels and loads of make-up.

Diana performed five songs from her debut album Songs From The Tainted Cherry Tree, including her new single Once, which is released today.

Crowd members described her performance as raunchy and said the singer looked was looking a tad worse for wear, stumbling on stage in her high heels.

We could hardly believe it was sweet little claw hands Diana flashing her crotch on stage.
