An artwork of Britney Spears' next single "I Wanna Go" from her new studio album "Femme Fatale" has just been unleashed. The single cover boasts a close-up look at the beautiful pop princess as she stares at the camera.

The single is produced by Shellback, Savan Kotecha and Britney's longtime collaborator Max Martin. A music video for the whistle-featuring tune is currently being prepared with director Chris Marrs Piliero serving behind the lens.

Beside gearing up her next single, Britney also gets ready for her summer tour with Nicki Minaj as a special guest. She is going to start the tour on June 16 at Power Balance Pavilion in Sacramento, CA and run it until August 13. The last tour stop will be a live concert at Air Canada Centre in Toronto, ON.

She additionally did album promotion by appearing as a cover girl for some major magazines including Harper's Bazaar. In its accompanying interview, she talked about many things including today's hot artists such as young singer Justin Bieber and outlandish performer Lady GaGa.

Commenting on Bieber, Britney said, "I think he's adorable. I just saw his movie, and I really didn't realize how big he was. He's enormous; he's just Mr. Man. A lot of the movie is really similar to what I did when I was starting out. I did a promo tour for a year, going into radio stations and all that. It was so cool to see our similarities."

As for GaGa, the "Hold It Against Me" hitmaker sang praise for her. "She's unique and extremely talented. I love her spin on everything," the Southern Belle gushed. She later mentioned Whitney Houston as her inspiration. "I've loved her since I was a kid," she stated.
