The actress is one of the executive producers of the new Emily Osment comedy and when show bosses needed someone to lock lips with their star in an upcoming episode, Tisdale volunteered.
She says, "I did a guest appearance, it's actually on July 9th... It was really fun... It's a really great role, something I've never done before.
"I play an editor of a magazine and I take a real big liking to Gabby, which is (played by) Emily - a real big liking to her."
But it won't be the first time she has kissed a girl: "I did it in another movie. I had experience... but when me and Emily had to do it, we've known each other for so long so it was like, 'This is going to be so awkward!'
"Emily went for it... and I was like, 'Woah!' When we came out of it, I said, 'That was pretty good'."
