The 22-year-old Teen Wolf star told Latina.com he and fiancé Seana Gorlick or set to tie the knot this fall.
"We've been very busy, but we've [been] able to start planning!" Tyler told Latina.com. "A lot of it is just talk. We're writing stuff down."
"Soon, we're going to get a wedding planner to come to us, and see what we can do. We've got the essentials down: it's going to be sweet and private and personal. Very relaxed...just like our lifestyle. I just can't wait!"
The thesp popped the question to his ladylove of 10 years during their vacation to Hawaii last summer.
"I didn't know if I was going to do it--I didn't have a plan or anything," Tyler told Us Weekly at the time. "I was so damn nervous."
After gaining some composure, the MTV star asked Seana to marry him before they headed to dinner on their first night in the Aloha state, pulling the ring out of a drawer.
"I just asked her and it was the coolest thing in the world," Tyler continued. "Her reaction was the sweetest--I can't even explain it!"
"I've known her since I was 11 and been in love with her since I was 12," Tyler went on. "I'm so inspired by her. I think she's the coolest, most raddest person ever. She's so nice and so cute."
Prior to their trip, Tyler told the mag he's known Seana was "the one" since middle school, adding, "I just want to be married to her--I want to be with her forever!"
