Ashley Tisdale claims it was "disgusting" having to kiss High School Musical co-star Zac Efron when he made a cameo on her show.

Ashely had to kiss Zac when he appeared on the Disney series The Suite Life of Zach and Cody.

However, she admitted the scenes were hard to play because she considers Zac to be more of a brother.

"I did kiss Zac though. But that wasn't in High School Musical. That was on Suite Life. That was behind closed doors. No, I'm just joking!
"That was disgusting actually. It was! He's my best friend and so he's like my brother and I've never been attracted to him cause he looked like he was 12 when I met him so..."

Ashley said the incident was made even more uncomfortable by the fact that Zac is also her best friend Vanessa Hudgen's boyfriend.

"So when I had to kiss him in the episode I'm like first of all it's my best friend's boyfriend and it's awkward enough. But it's like kissing your brother almost... But he made it really fun and comfortable."
