"I didn't know if I was going to do it — I didn't have a plan or anything," he said. "I was so damn nervous," he recalled. "I just asked her and it was the coolest thing in the world. Her reaction was the sweetest — I can't even explain it!"

He might be off the market but you can still watch Posey in all his glory on Teen Wolf. The series airs Mondays at 10/9c on MTV.
