Also in music news, Rihanna thinks ex-Disney diva Demi Lovato is "gangsta," Tony Bennett's nude sketch of Lady Gaga is up for auction, and it's Taylor Swift's birthday! Everyone go hug a cat.

Rumored "booty call" buddies Cameron Diaz and Diddy were spotted causing a hot, sexy scene at the Dream Downtown Hotel's PH-D on Saturday night. Witnesses spotted Diddy making his way to Cameron Diaz's table at about 1:15 a.m., and after some Ciroc cocktails, the two were "kissing and making out."

Diaz and Diddy have been spotted together several times, but her rep claims they're "just friends."

Just friends who swap spit, that is.

We won't be at all surprised if about six months from now Cameron decides she wants to make an over-hyped, over-produced R&B album under the name "Cammie D."

Rihanna has a new favorite pop star: Demi Lovato. She followed her typically raunchy tweet, "I love it I love it I love it when ya eat it" with "Demi Lovato goes so hard!!! She gangsta."

Lovato was obviously thrilled to be the first ex-Disney channel regular in hist! ory to b e called "gangsta," so she responded almost immediately: "Only cause I learn from the best!! Aka YOU!"

Maybe this means that a couple years down the line, Demi's going to look to Rihanna's onstage costumes for sartorial inspiration:

The nude sketch of Lady Gaga that legendary crooner Tony Bennett created for Vanity Fair is available for purchase, with proceeds to benefit Exploring the Arts, Inc. Bids have reached $5,400, and with several days left on the eBay auction, it appears that the charcoal sketch will snag a nice chunk of change for charity. But fear not: The sketch comes with free shipping!

Taylor Swift is 22 today! The country superstar is spending her big day in the studio, but she did have a chance to drop by her record label, where she was presented with this:

Cute, but how does it stack up against these amazing celebrity birthday cakes?
