Britney Spears Talks Sex in E! Doc ‘I Am Britney Jean,’ Reveals Full Las Vegas Residency Set List

“I love sex, I think sex is great,” the songstress said. “But I feel a little different about it now that I’m older”

Britney Spears‘ two-hour E! special, “I Am Britney Jean,” showed the numerous sides to pop star Sunday night, five days before her Las Vegas residency raises its Planet Hollywood curtain.

“Britney: Piece of Me” kicked off rehearsals on Dec. 10, and the former teen sensation filmed it all for the E! documentary. The special showed the performer, producer and co-director choosing her set list, designing the stage and hand-selecting costumes for herself and the backup dancers.

There was also, of course, footage from the singer’s personal life as a mother, daughter and girlfriend. In the piece, Spears did not shy away from her issues in the past, including 2007’s now-infamous breakdown, referring to herself as “bipolar.”

During the grueling show set-up, Spears simultaneously filmed her music video for single “Work Bitch,” the sexual nature of which she commented: “I love sex, I think sex is great. But I feel a little different about it now that I’m older. Sometimes I feel like I’m like 20, and sometimes I feel like I’m 50.”

Even if she might not need the fat paycheck that the 50-show-per-year Sin City platform will afford her, Spears could use the promotional push for her new album, “Britney Jean,” which has not exactly been lighting the Billboard charts on fire. Her latest offering bowed to just 107,000 opening week sales, good enough for just No. 4 on the Billboard 200 and marking her lowest launch to date.

By comparison, with no promotion whatsoever, Beyonce’s self-titled secret album sold 80,000 copies in just its first three hours alone. By the end of the sales week, of which “Beyonce” existed for only three days, Mrs. Carter’s iTunes-only release was up to 617,000 purchased downloads.
