Britney Spears Las Vegas Tour Rider? Cheetos + Cheeseburgers

We can hear her arteries hardening! The rider for Britney Spears' Las Vegas residency is loaded with junk food and empty calories. Thankfully, the singer is dancing harder than she ever has in her life, since she'll need to work off these eats.

Brit's going to be in residency at the Planet Hollywood Resort & Casino as of Dec. 27 and she asked for a mountain of lowest common denominator vittles in her dressing room.

"Britney is insisting on Froot Loops, Pop-Tarts, Cap'n Crunch, Gatorade, Doritos and potato salad," a source said. Not exactly the five food groups. Where are the fruits and veggies, Brit Brit?

In addition to asking for a supply of In-N-Out cheeseburgers without buns -- she must be cutting down on carbs -- she has also requested a life coach on call all day, every day.

That, and 200 fresh towels a day.

Brit, who confessed to being in lurve with her BF David Lucado, won't be on her own in Sin City. Lucado will accompany her. An insider said, "He will live with the singer during her residency. Her team is OK with it just as long as she's happy -- that's all they want."

Brit's residency squad includes a chef, an assistant, a driver, security, a voice coach, a hair stylist and a makeup artist.

Sounds like she might need to add a nutritionist to the payroll.
