Two tracks, 'If I Were a Boy' and 'Single Ladies,' will be released in advance of album.

While details have been largely kept under wraps, some information has emerged about Beyoncé's forthcoming, still-untitled third solo LP, which is slated for release on November 18 on Music World Music/ Columbia.

Justin Timberlake will appear on the LP, although further details on his involvement were not available at press time. The two sang together on a cover of the 1968 Marvin Gaye/ Tammi Terrell hit "Ain't Nothing Like the Real Thing" at the Fashion Rocks concert in New York last weekend.

Timberlake told reporters outside the show, "I'll be in the studio this week with Beyoncé. Who knows what will come out of that?" according to MTV News U.K.

Beyoncé co-wrote or co-produced all the material on the album, which the label says comprises "her most personal, reflective and revelatory collection to-date."

Songwriter/ producer Sean Garrett (Mary J. Blige, Usher, Fergie) revealed to MTV News on the VMA red carpet that he's been Beyoncé's album. "I got to get a big secret out: Beyoncé!" he said. "I just finished some incredible records with her. She's probably going to be mad at me for telling you all — sorry, B!"

Producer Jim Jonsin (Lil Wayne's "Lollipop," T.I., Danity Kane) reportedly worked with the singer on the song the track "Beautiful Nightmare," which leaked earlier this year, although it was unclear at press time whether the song will appear on the LP.

Two tracks from the album, "If I Were a Boy" and "Single Ladies," will be released in advance of the LP on October 7, according to the label. Beyoncé filmed a video for an undisclosed song in New York on Thursday.

Beyoncé also has two films in the works: She appears as legendary singer Etta James in "Cadillac Records," which does not yet have a release date, and the wife of a man being stalked in "Obsessed," due early next year.
