The body of Sage, 36, was discovered Friday afternoon and an autopsy was conducted over the weekend. The official cause of death won't be determined until toxicology reports are completed in the coming weeks.

Braunstein told ET that Sage had been planning on getting married this past weekend in Las Vegas, but that he wasn't engaged, so it was meant to be a spontaneous event.
