Britney Spears believes her Las Vegas residency is "ideal" as she won't have to travel too much.

The "Work Bitch" hitmaker is set to launch Britney: Piece of Me at Planet Hollywood next month, and she is looking forward to the short commute between her home in Los Angeles and Sin City after three "grueling" years of touring:

"I've done two tours in two years in the past three years and it's so grueling, being on the road and staying in a different bed every night. The schedule is insane. I thought it would be ideal to have one place I could go to and I could just travel back and forth to my home after the show. It's going to be different but I'm excited."

The 31-year-old star - who has sons Sean Preston, eight, and Jayden James, seven, with ex-husband Kevin Federline - also opened up about writing her new album, Britney Jean, which she says was like "therapy." Britney admits to feeling "reclusive" at times and having "harder" days in her life, but writing her eighth studio album sparked her creativity.

"I would say the album was kind of like therapy for me. It just kind of transformed me. I'm an artist, so I think there are periods in everyone's life where you get kind of reclusive, your creative outlet is cut off... then sometimes it flows and you're like, 'Oh my God, this is what I need to be doing,'" she said in an interview with Entertainment Tonight, which aired last night.
