Madonna's after party must have been incredible!
Not only are were positive they had the best of the best food and drink wise, but they had Sean Penn busting moves!
According to a partygoer, he witnessed the Madonna herself and Sean Penn submit to the uncontrollable urge to dance!!
"Jus got back from Guy O party. Never been around so many wasted stars. When u c Penn dancin wit Madonna in 2011 u know it was off da chain."
Very… eloquent. LOLz!
Point is, Penn and Madonna were gettin' down!
We'd love to see that!
