Kid Cudi Faints During Concert in Chicago (VIDEO)

Kid Cudi was signing an autograph for a fan during his show in Chicago on Saturday night when he passed out and was carried away by several security guards. 

Cudi was performing at the North Coast Music Festival and the video shows him clearly covered in sweat. He appeared fine one moment ... and was laying on the floor the next.

The rapper seems to be fine though, he sent out a series of tweets after the show, saying, "Mad love to the security who were there and helped me out tonight. Really awesome dudes! Thanx for nursing me back to health ha ... Ill do a better and make sure to eat properly on show days :) scouts honor! ... If I scared anyone tonight I am so so sorry from the bottom of my heart."
