The scene in question? When he had to kiss Jocelyn Shelfo as Madison in the club scene.

“So there was a scene where I was kissing Madison the first time,” he continued. “And I can see Gia all the way there, behind the DJ booth set. I told Gia, ‘Just get down.’ Like, go away. And she’s like, ‘No!’ I’m like, ‘What do you mean, no?! You want to see your brother kiss someone?’ I think that was my far most awkward and embarrassing moment.”

Gia added, “But, you know, I didn’t actually see you do that.”
