Your boyfriend Adam Levine is pretty much the guest of honor everywhere

It’s no secret that celebrities routinely get paid to party. Sometimes these stars also have to, you know, provide some manner of entertainment between drinks;  2 Chainz, for example, hung out and rapped at Los Angeles’s Supper Club over the Labor Day weekend in exchange for $35,000. (No word on whether his set list was based on his upcoming album, B.O.A.T.S II: Me Time. But something tells me that his tour rider required all ho’s on D.E.C.K.)

Other times, stars just have to show up, maybe walk a red carpet, glad-hand a starstruck corporate host or two, and pretend to enjoy their complimentary bottle service. Heck, Kourtney Kardashian reportedly demanded $150 from every fan who simply wanted to get a photo with her in Las Vegas recently.

Living legends such as Elton John can command upwards of $1 million for private appearances, I hear. But that price tag doesn’t make him the most sought-after celebrity guest of the moment.

“Right now it’s all about the people from The Voice, the judges,” says Rita Tateel, a professional celebrity wrangler who pairs stars with brand endorsements and private events. “They’re the people who are really in demand.” In fact, in the world of, say, corporate events, “You’re talking about A-plus talent.”

As for how much Adam Levine or The Rest of Them might charge, consider this fact: They’re in higher demand than, say, an America's Next Top Model contestant, who might charge “like, $2,500, sometimes $5,000 tops,” Tateel tells me.

Then there are the Real Housewives. Those lippy old battle axes command about “$7,500 to $10,000” per appearance, which might include signing autographs or giving a talk about the show.

Of course, I drilled down, asking Tateel precisely how much it would take for Adam Levine to come to my, um, belated premiere party for the Fame Fatale, an event I totally did not make up just now.

“I don’t even know if they would do it at all,” Tateel says frankly. “its not all about the money. We were supposed to do an event recently with a legendary comedian, but then she changed her mind.

“She was like, ‘You know what, I don’t feel like flying from here to there, and I am going to take the night off’.”

What if I threw in this lovely Fame Fatale travel mug?
