No one forgets his or her first kiss. But not many can say
it was Miley Cyrus -- unless, that is, you’re Tyler Posey.

While talking to ETonline, the 23-year-old star of MTV’s Teen
Wolf recalled the time he locked lips with the pre-Hannah Montana
starlet. The moment came at 9-years-old when he was working on the PAX medical
drama, Doc, with Billy Ray Cyrus.

Posey and his daughter Miley bonded after moving to
Toronto where the show was filmed. “I was basically the only kid on set.
She would come on set every now and then and we became really good friends,”
Posey recalled. “We were both goofy and she was really loud, sweet, and funny
-- just a really cool kid.”

The two eventually became a couple, spending two years as
“boyfriend and girlfriend” during which time he had his first kiss. “We were so
damn young… I would get excited when we would hold hands,” Posey said.

While they never evolved into a serious relationship, Posey
could tell, even then, that Cyrus was a special, self-assured person. “She was
herself at seven years old. She knew who she was,” he said. “I never met anyone
like that at my age.”

In the years since their pre-teen romance, Posey was in
12-year relationship with Seana Gorlick. The two separated in October 2014. And
Cyrus, now 22, revealed that she came out to her mother when she was 14 years
old.

Posey’s appreciation and understanding about who Cyrus is
-- even though they were both just kids -- extends beyond just the singer. In
fact, the actor has several gay family members and best friends.

“It's a huge part of my life,” Posey told ET about the LGBT
movement while on the red carpet at Logo’s second annual Trailblazer Honors.
“I’m a huge advocate of just being yourself.”

“It's really cool to be part of the generation that is
experiencing all of this love,” he added.
