Criminal Behind The Scene!

Since Britney Spears arriving in the U.K., the singer has been hard at work on the set of her "Criminal" music video, according to photos that hit the Web. The pics reveal there will be a cameo from a super special guy in her life.

In one photograph, a smiling Spears holds a gun as she leaves a convenience store with her real-life boyfriend Jason Trawick behind her. Other photos show Spears inside the store tucking the gun in the waistband of her pants, and Trawick carrying groceries and pulling Brit by the arm. In a chat with AOL, the pop star explained that it was her idea to shoot the clip in London. "I'm shooting a video [and] I've never shot on location out of the country of America for a video," she said. "So, it should be very interesting. It was partly my idea ... to see if it could to happen, and they were like, 'Yeah, it's a great idea,' so we did it."

The Femme Fatale singer also opened up about her busy career, including the European leg of her tour which kicks off this month. So, how does she stay tour-ready at all times? "Sometimes it is [a lot of work], but I genuinely love what I do and I get on a routine and a schedule to keep me motivated and inspired to have the energy I need for the show," she said. "A lot of cardio, a lot of running and just try and eat clean."

Britney added that it's all about balancing motherhood and career. "You just have to find your balance and niche in your life," she said, crediting her mom and nanny with giving her a helping hand. "It's a process you learn to figure out."(mtv)
