We reported last night that Green Day frontman Billie Joe Armstrong checked into a rehab facility after having an onstage meltdown at the iHeartMusic Festival this past weekend. Our friends over at UpRoxx took note of Armstrong's profanity-laced rant and found 10 other instances of musicians losing it during a performance. These include The Notorious B.I.G. throwing a water bottle at a DJ, Ashlee Simpson doing a jig on Saturday Night Live, and Wavves frontman Nathan Williams buggin' out at 2009's Primavera Sound.
