Check out Madonna's brand new video for her song, "Celebration."

At 51, Madge can still get down -- and she's got a reason to dance -- as her gorgeous young boyfriend, Jesus Luz, struts around this video with barely any clothes on. 

Also, Madge's daughter Lourdes is showing that she's inherited some of her mom's love of the spotlight, as the 12-year-old makes a super-fast, back-flipping cameo just after the 3-minute mark.

Are you ready to party with Madonna's new song?
