"Deja Vu" is the first single from Beyonce's upcoming album “B'Day�? which will be released worldwide on Sept. 4, her 25th birthday, and Sept. 5 in America.

Beyonce Knowles worked hard for her new video "Déjà vu" in the swamps dodging alligators, snakes and bees.

According to contactmusic.com, Beyonce revealed that she sweated throughout the shoot but is happy with the final cut. The video features her boyfriend Jay-Z too.

She says: "I decided to go to Louisiana because it has a soul that a studio can't give you. We were in the swamps. Literally, there were alligators, snakes, bees and wasps. It was 105 degrees. All of that sweat in the video is real. That's not some spritzer. That's real."

Meanwhile Beyonce Knowles has revealed the secret to her sexy curves is cereal.

The singer-turned-actress says she eats the breakfast treat through the day to stay in shape and to curb hunger pains.

She said: "My big fitness trick is cereal. I love it - granola cereal in particular."

Beyonce discovered the benefits of cereal after being told she had to shed 20 pounds for her role in new movie Dreamgirls.
