Matt Thiessen: Matthew Arnold "Matt" Thiessen (born August 12, 1980) is a Canadian-American musician, singer and songwriter known for being co-founder, lead singer, guitarist, pianist, and primary songwriter for the Christian rock band Relient K.  With Relient K, he has released eight full-length albums, including three that were certified Gold, and three that peaked in the top twenty on the "Billboard" 200.

My Girlfriend (Relient K song): "My Girlfriend" is a song by the Christian rock band Relient K, released on their self-titled first album.  The song originally appeared as "Marilyn Manson Ate My Girlfriend" on the band's demo album, "All Work and No Play".  The song is about Marilyn Manson eating Matt Thiessen's girlfriend.  Thiessen wrote this song when he was 15 years old.  Thiessen has said that he wrote it because of a female friend, who lived eight hours away in Pennsylvania, who he would talk to about many things including spiritual matters such as where God was taking them in the future.  His friend would later turn from Christian music to Nine Inch Nails and Marilyn Manson.  In an interview with CCM Magazine Thiessen stated "through this she changed her lifestyle [and] what she believed in."  His friend would later be expelled from school and would be kicked out of her house and sent to a youth detention center.  Thiessen would later state "She felt that Christianity was stupid and just this big hypocrisy.  Being young and impressionable, I just wrote this little, stupid song, but that was the way I dealt with it—writing this song about how she got so consumed by Marilyn Manson."
