How did we NOT know about this?! This is CRA-AAAAZY!
Check out this 1979 music video by one-hit-wonder Patrick Hernandez for the track, Born To Be Alive, (above) which also features a surprise blink-and-you-miss-it cameo from her madgesty herself, Madonna, as a back-up dancer!
The iconic pop star is featured as the only dancer in the first row, and there's a brief close-up of her around the 2:01 mark, so give it a look!
So crazy! Thankfully, as we all know, she moved on to bigger and MUCH BETTER things relatively soon after this mess!
