At Puddle of Mudd's Dallas concert April 16, singer Wes Scantlin appeared to be lip syncing.

Fan-filmed video also seems to show Scantlin in a confrontation with an audience member, reportedly who called him Milli Vanilli.

Scantlin eventually left the stage but later returned, throwing bottles and his microphone.

Watch fan-filmed video from the show below (warning: not-safe-for-work language). Fan posts to the band's Facebook page were not flattering of the concert.

Scantlin's recent history has been tumultuous, having been arrested for battering his ex-wife, being involved in a hit-and-run, arrested for vandalizing property, and more.

At :58 of this video, Scantlin puts the microphone into the audience, but his voice can still be heard singing:

At 1:12, Scantlin throws the mic, in frustration after being cut off by the soundboard.
