Why Ashley Tisdale’s Daughter Thought Zac Efron Is Her Dad

8. The sibling rivalry was just as real off-screen as it was on-screen for Ashley and Lucas… at least at first. “We weren’t close. We weren’t good friends … we hated each other,” Ashley admitted in a video she recorded with Lucas for her YouTube channel. Lucas added that the pair “didn’t get on the best of terms” when they started filming the first movie, but eventually became close friends. How fabulous!

9. In an interview with Buzzfeed, Lucas revealed that he pushed for Ryan’s sexuality to be explored early on. “After reading the script, the first thing I said to [Kenny Ortega] was, ‘OK, Kenny, Ryan’s gay, right? I know it’s Disney Channel, so I’m not really gay, but I mean, yeah, right?’ And he’s like, ‘Well, think about it this way: you have the opportunity to play a character who’s young, he’s in theater, he’s an artist and let’s go at it from that point of view,'” Lucas explained . ‘He talked to me about his own life and he said: ‘I see a lot of myself in Ryan. Yes, I knew I was gay in high school, but I didn’t tell anyone.’ It was about making it real.”
