As Mariah Carey prepares to release her new single, "Heartbreaker," to radio next week, the R&B songstress has just christened her upcoming studio album "Rainbow."The new record is Carey's much anticipated follow-up to 1997's "Butterfly" and will feature her first batch of studio material since the three new tracks that were included on last year's compilation, "#1's." On Monday, August 16, Mariah Carey will world premiere her video for "Heartbreaker" on MTV at 10:30 p.m. The clip for "Heartbreaker" was directed by Brett Ratner and features an appearance by Jay-Z, who also co-wrote and raps on the track (see "Jay-Z, Mariah Carey Break Hearts Together"). DJ Clue also lends a hand on "Heartbreaker," and as the songstress revealed to MTV News, the remix has some girl-power surprises in store. "It's pretty much [in] the classic style of my up-tempo classics like 'Fantasy' or 'Dream Lover,'" "I'm so excited about the remix. It's also gonna go on the album, and it features Missy Elliott and Da Brat, and it's kinda like a girl-power answer record, and it's to the loop of Snoop [Dogg]'s 'Ain't No Fun.' They're not ready for that one!" [RealVideo] "Rainbow" is tentatively set for release in November, while "Heartbreaker" will be issued as a commercial single on September 21.
