Jessica Simpson, Giant Boobs to Host Pussycat Dolls Performance

Take this, Nick Lachey!

You may be moving in with long-time girlfriend Vanessa Minnillo, but your ex-wife is taking her big boobs to the stage in Las Vegas.

That's right, Jessica Simpson is getting back to her cleavage-baring ways.

The brown-haired owner of two really huge breasts will don her naughty-wear May 4 when she plays host to a special performance by the Pussycat Dolls at the scantily-clad group's themed lounge at PURE nightclub in Las Vegas.

"This is a chance for her to be sexy again and back in the spotlight," a club source said.

After all, Simpson has almost taken a back seat to John Mayer throughout this famous pair's relationship. But not anymore! Not if Jessica Simpson's bare skin and voluptuous curves have anything to say about it!

And as Tricia Helfer has proven, those assets can take you far.
