Aisleyne Horgan-WallaceWhose bottom?Actually, we're not that shocked.

We feel like we've seen this butt before...

In fact, sometimes we worry we've seen Aisleyne Horgan-Wallace's bottom more than our own.

We've spotted the former Big Brother housemate rocking up to many a red carpet premiere or nightclub in a skimpy, barely-there outfit...

This time the paps caught Aisleyne flashing her cheeks at the launch party of the Wardour Club in London.

But what never ceases to amaze us is Aisleyne's courage.

Does this girl have no shame?

Clearly not.

Take a look at Aisleyne and other member of the Skimpy Kit Gang in the gallery above.
