AceShowbiz - Dean McDermott is proudly speaking out of his trans kid. The actor has revealed that one of his children,

whom he shares with his rumored estranged wife Tori Spelling, has come out as transgender.

The Canadian actor spoke out about his trans kid for the first time during the premiere of his latest movie "My Fake Boyfriend".

In a video posted on his eldest son Jack's Instagram Story, the father of six acknowledges that 15-year-old Liam now identifies as transgender.

"The thing I love about this movie is I got to share it with my 15-year-old who identifies as trans and my gay son," Dean said in the clip, as the audience broke out into applause.

"I love that they get a safe space to come and watch this."

The 55-year-old added of the film, "I think this movie is really important. It's as poignant as it is fun."

He further gave a shout-out to his two aforementioned children, "So, thank you all for coming, and most importantly, to Jack and Liam, I love you guys."

While this is the first time Dean spoke about his trans kid, he had posted a series of pictures of him celebrating Pride with Jack and Liam last week.

Tori has not spoken up about her kid Liam, who identifies as trans. Recently, she opted to spend Father's Day with her daughter Stella, her pal Lance Bass,
