Hayden Panetierre made a big announcement about her love life prior to the release of her upcoming memoir, “This Is Me: A Reckoning” (Grand Central Publishing).

The 36-year-old actor publicly came out as bisexual in an interview with US Weekly published Wednesday.

It’s something she said she has kept under wraps for years, despite being “much more into women” than men while she was growing up.

“The first time it even crossed my mind to touch on this subject was while I was in the process of writing this book,” Panetierre admitted to the magazine.

Panetierre, known for her roles on “Heroes” and “Nashville” as well as her previous engagement once upon a time to former heavyweight boxing champion Wladimir Klitschko, said that she’s chosen to “be completely brutally honest about” her sexuality and said she was never able to do so before “because it was just never the right time.”
