OMFG Jennifer Lopez is back - with a VENGEANCE!

It was 1999 when Jennifer Lopez marketed herself as a singer. Her first single became a huge hit, the track "If You Had My Love" became her first number one on the Billboard charts and later became one of her signature songs.

Now its 2011, she has kids now but damn, she is still one hot lady, still with a body to boot! Her new music video for her latest single "On The Floor" is out now! One hot track indeed.

Watch the video after the jump!
