In case you didn't know -- Madonna is pretty damn cool. And it turns out she is a pretty damn cool mom. Madge's 13-year-old son, Rocco Ritchie, just posted Instagram pics dancing with his famous mom while on a recent charity trip to Haiti. And the mother/son duo look like they are having a blast!

We definitely think the Material Girl has passed on some of her famous dance moves to her son! While most teens would be embarrassed to have their mom flamenco dance around with them -- Rocco is clearly loving it. And most kids don't have Madonna as their mom!

In the pic, the 55-year-old icon holds her hip as she dances with a fan as her teenaged son gets into the groove behind her. The Holiday singer showed off her arms of steel in a tight black T-shirt with the slogan, "Defend coexist' printed across it.

On November 25, Madonna and Rocco flew to the Caribbean country devastated by the 2010 earthquake in order to support her ex husband's J/P Haitian Relief Organization. During the charitable trip, Guy Ritchie's son posted pics from hospitals and while visiting a number of children in need. At one point after visiting the hospital in Mirebalais, the pop progeny wrote, "Hospitals will make you say, sh*t I'm lucky."

Yeah, you are kid.
