Kim and Kanye do Vegas (and Kanye turns down half-mill gigs in Britney’s room?)

TMZ says Kanye West turned down a deal in Vegas to do $500,000-per-show for nine shows, equaling $4.5 million.

But Caesars Palace has no information to provide us about that story (which claims the deal would put Kanye in Britney Spears’ Axis Showroom), and Caesars said this officially about J Lo’s rumored offer:

“Jennifer Lopez has not been presented with any offer to perform at Planet Hollywood Resort & Casino,” Caesars says.

What’s interesting about the Kanye rumor is: $500,000 per show would barely equal what several DJs earn in Vegas routinely — and those DJs do less work with far fewer crew costs.

But different stars draw different demographic audiences, obviously.

What Planet Hollywood really should offer is: “Kim and Kanye on stage with Bruce Jenner.” Now that would be a show.

Meanwhile, Kanye and wife Kim Kardashian West were in Vegas over the weekend. He performed at the Life is Beautiful Festival.

And he joined her at her annual birthday party at Tao nightclub in the Venetian.

Check out all the photos we have of that, by photographer Denise Truscello/WireImage. Tell us what you think about sweet lil’ Kim, and that dress, and everything, down below in our always-riveting comments section, please, thanks, you’re great.

By the way, J Lo launched the current trend of lady stars who exhibit butts that are not skinny, and Kim made that trend explode to the point that plastic surgeons are rolling in dough after fattening up booties across the nation (but mostly in Hollywood and, I guess, Miami?).

America: We got ass.
