Six years after the singles from Britney Spears' first four albums were reworked for "B In The Mix: The Remixes," the pop princess has collected recent remixes by Tiesto, Kaskade, Benny Benassi and others for "B In The Mix: The Remixes Vol. 2." Due out Oct. 11, the 10-song album features new versions of tracks from 2007's "Blackout," 2008's "Circus" and "Femme Fatale," which hit No. 1 on the Billboard 200 last March.

"Exciting news tweeps... new remix album is coming out on 10/11!" Spears announced on Twitter on Friday (Sept. 9). "Pumped for you to hear these tracks - I love them."

Among the album highlights are Manhattan Clique's club remix of "3," Gareth Emery's take on "I Wanna Go," Tiesto's club mix of "Piece of Me," and Alex Suarez's reworking of "Till the World Ends." The album art finds Spears striking a seductive pose in front of a pair of butterfly wings.

2005's "B In The Mix: The Remixes," which featured club-ready versions of "Toxic," "Me Against the Music" and "I'm a Slave 4 U," among others, has sold 119,000 copies according to Nielsen SoundScan. "Vol. 2" will be released in the middle of the European leg of Spears' Femme Fatale tour, which resumes Sept. 22 in St. Petersburg, Russia.
