Fans believed the couple was in a committed relationship before it split following an alleged fight at the Coachella festival in April, but now it appears the actress and Mod Sun were so much more than just lovers.
The 32-year-old tells TooFab Bella was his wife.
"That's what young crazy people do, bro," he says. "I got engaged, married and divorced in 15 months in Hollywood. That's what we do out here in these streets. We out here putting rings on it, that's what our generation does."
The former couple recently fell out after Mod Sun threatened to sell off all the personal items Thorne had left at his pad before it split.
Bella has yet to comment on her ex's marriage claims.
