"I’ll tell you why it was the worst, okay? I had to kiss Zac Efron on The Suite Life of Zack and Cody, and it’s the worst because I am so close to him and he’s like my brother," she shared in Elle magazine’s "Thirst Trap" segment.
"At the time, he was used to acting on, like, Warner Brothers, which is CW, and we were on Disney Channel," she explained. "And so he, like, he tried kissing me with his tongue, and I was like, 'Get away from me!' I closed my mouth so fast."
"I was like, 'This is Disney Channel, we don’t kiss like that on Disney Channel!'" recalled Tisdale while laughing, nothing that it was awkward because they had been friends for so long and had already filmed HSM.
"It's just weird when you're so close to somebody, and we’d already done the movie. I’d known him for years before," Tisdale explained. "That is why it was the worst. It’s just we’re too close."
During the segment she also had to choose between her Suite Life of Zack & Cody co-stars, Cole and Dylan Sprouse. When asked who she would rather spend three weeks in a remote location with, Tisdale chose Dylan.
"They're both like my little brothers. You know who texts me back, like all the time? Dylan Sprouse," she said. "He's the one who texts me back. Cole, sometimes silence. So I'm taking Dylan."
Last month, Tisdale appeared on an episode of Watch What Happens Live With Andy Cohen, where she played a game of "Shag, Marry, Kill" and had to pick between the Sprouse twins and Efron.
