After a seven-year hiatus, Whitney Houston will release a new album Sept. 1, her record label announced Wednesday.

Houston's seventh studio album - rumored to be titled Undefeated - will include the Diane Warren-penned "I Didn't Know My Own Strength."

Photographer Patrick Demarchelier recently worked with the singer for some promotional shots and called the day "fantastic." "She was so full of life and energy. She moved well and was in such great spirits," he said.

Houston, who divorced ex-husband Bobby Brown in 2007, has sold more than 170 million singles, albums and videos worldwide and is cited by the Guiness Book of World Records as music's "most awarded female artist of all time" with a tally of 411 awards, including six Grammys and two Emmys.
