In a recent interview with The Huffington Post, the Journey musician revealed that he and Salahi are "headed toward marriage".
The 58-year-old rocker began dating Salahi in 2011, after she divorced husband Tareq Salahi.
Tareq later sued Schon for allegedly stealing Michaele from him.
Schon denied this and other allegations of harassing Tareq over the phone, insisting: "I've always taken care of situations like this behind closed doors, and this is the first time in the last five months that I have been in the media... But Tareq chose to put it out there."
Schon said that he has known Michaele for over 15 years, and that his bandmates approve of the couple's upcoming nuptials.
Michaele Salahi rose to infamy after crashing a White House fundraiser while filming the now cancelled Real Housewives of DC.
