Amerie is packing her bags and moving her album from September to November.

The R&B siren’s fourth album In Love & War has been pushed back to November 3. It was previously scheduled for September 29. A new single, “Heard ’Em All,” was released last week.

Amerie is pleased with the new date. “Very happy w/my album date! Got the one I wanted,” she tweeted. “So I’m officially putting it out there: In Love & War — November 3, a special date…”

In Love & War will feature production from The Buchanans, Teddy Riley (“Tell Me You Love Me”), Sean Garrett and Eric Hudson (“Heard ’Em All”), Jim Jonsin and Rico Love (“Swagback”), and Bryan-Michael Cox (“Red Eye”).

Upcoming appearances include the 2009 MTV Video Music Awards (Sept. 13) and VH1 Hip Hop Honors 2009 (Sept. 23).
