Britney Spears' Femme Fatale Tour is a glittering, over-the-top spectacle, complete with multiple costume changes, set changes, and a fleet of backup dancers and stage performers. Another major part of the tour is the other acts who are on the road with the star. MTV News caught up with tourmates Joe Jonas, Nicki Minaj and "Drop Dead Beautiful" rapper Sabi on their New Jersey tour stop, and they gave us an inside look at what it takes to get this show on the road.

"Behind the scenes, there's a lot of security, lots of salad and lots of cranberries and almonds, lots of dancers stretching," Spears' tourmate Minaj joked from her dressing room. "There's also a lady that comes every day and gives massages. She has like a massage chair and every time I go out there, she's giving some bloody bloke a massage," she teased in her signature British accent.

Brit's show isn't the only one that incorporates multimedia displays. Nicki's opening slot goes above and beyond thanks to video packages and costume changes. "Well, definitely I wanted my set to be more than an opening act 'cause, you know, I did that already," she said. "I always like to raise the bar for myself and that's what I did. I think it's important to give people what they paid for."

Sabi said that hours before the show happens, there's lots of hustle and bustle to make sure everyone is in the right state of mind. "It's crazy to see how wardrobe is rushed from one location to the next, or if there's something wrong with the shoes or there's extra shoes and dancers need massages and the catering's not here till 5 and we have to eat at 5 o'clock and everybody rushes to catering," she explained of all the hubbub."It's pretty fun and hectic back here, but it's dope."

During the show, Sabi hits the stage alongside Brit to perform their Femme Fatale track and she says that being up there in front of the sea of pop fans is "kind of hard to describe," adding that, "it's bananas. I get the biggest rush ... it's crazy.

"I've learned how she just delivers. There can be a bajillion things going on and she just delivers every time," Sabi said of Spears. "I'm learning the professionalism of it."

Jonas kicked off his time with Spears in his home state of New Jersey and said that he was stoked to be there. "[I'm] very excited right now. I can't wait," he said in his dressing room. "Getting up on the stage felt really comfortable, so I think it's gonna be really fun. Like everyone out there, I'm a fan of Britney, and it's New Jersey, so it couldn't be more perfect."

Nicki certainly has plenty of pop music crossover appeal and says that performing in front a pop crowd has worked well for her. "Honestly, it's been epic," she said. "They have an amazing spirit, a great vibe, and it's love every night, and I would not have traded this experience for anything else in the world."
