Singer Demi Lovato may have joined a list of celebrities who have come out as bisexual.

The former Disney darling got coy about her sexuality on a TV show when asked about the meaning behind her new song "Cool for the summer", which includes lyrics like "got a taste for the cherry, I just need to take a bite", reports aceshowbiz.com.

"Can you confirm or deny that (the song is) about lesbianism," asked "Alan Carr: Chatty Man" host.

Lovato said: "I am not confirming and I'm definitely not denying. All of my songs are based off of personal experiences. I don't think there's anything wrong with experimentation at all."

The openly gay British host Alan Carr then said: "I experimented once and it stuck", to which Lovato responded: "Hey, I didn't say that it didn't stick either. I didn't say that it didn't stick."
