Her new song, "Work Bitch," is a dance anthem, but Britney Spears says her upcoming album, which is due out in December, features more than a little heartbreak, People reports.
"It's the most personal album I've done," Ms. Spears, 31, admitted Friday on "On Air With Ryan Seacrest." "After having a huge breakup this year, I had a lot to say in the studio. So it was really nice to have a therapy like that and to be able to share that with my fans. ... So it's a real personal album."
The "huge breakup" she's referring to is her January split with fiance Jason Trawick.
The mom of two -- who's set to begin a two-year residency at Planet Hollywood in Las Vegas on Dec. 27 -- isn't worried about reliving the bad times with her ex when she performs the songs.
"Usually the stuff that really comes from the heart is usually the best stuff and has the best beat and really kind of helps you get over the breakup really easy, 'cause you sing about it and have to think about it every night, but then you're like, 'It's OK! I'm performing now so it's totally fine.' "
