The shock rocker started dating 'America's Next Top Model' winner Caridee English after the pair met at a recording studio where the model was recording vocals for her debut album.
CariDee said: "Marilyn Manson inspires and supports me in my music. He has made me feel comfortable and beautiful with who I am as an artist and as a woman."
A source added to Life and Style magazine: "They've been seeing each other ever since they met. She loves how different he is."
Blonde CariDee has dyed her hair dark and reportedly recorded a cover version of her new boyfriend's song 'Coma White' after the new couple reportedly bonded over their love of music and fashion.
Marilyn was seen partying with a group of mystery in Women in August to get over his break-up from Evan.
The pair first separated in October 2008 before briefly reuniting in February 2009.
The pair rekindled their romance last December before finally splitting earlier this year.
