The 'Rock of Love' bus may still be parked for Bret Michaels, but Machine Head guitarist Phil Demmel and Bleeding Through keyboardist Marta Peterson are on the road to marriage. According to Blabbermouth, the Machine Head guitarist just revealed via his personal Facebook page that he and Peterson are officially engaged.

The rock couple have been dating since Machine Head and Bleeding Through toured Australia and Japan together in early 2010. Demmel shared his memories of meeting the Bleeding Through keyboardist with Hardrock Haven. "I met the girl of my dreams in Australia the last time we were down there," declared Demmel. "One of the greatest things that has ever happened to me was on that run. I have very special memories of Australia and knowing that I was in love for the first time when I was in Brisbane."

Demmel is already a father of a five-year-old son, Jadon Philip Demmel, who he had with rock model and blonde bombshell Jamie Jagger.

Along with being an accomplished musician, Marta Peterson has also gathered praise as a rock 'n' roll sex symbol, having been featured in several of Revolver's "Hottest Chicks" in metal and hard rock features.

Machine Head are currently riding high from their 2011 release 'Unto the Locust' and will continue to tour internationally starting on Jan 15. Bleeding Through's seventh studio album 'The Great Fire' is set to be released on Jan. 31.

Congrats Phil and Marta!
