ACTOR LIEV SCHREIBER attended Comic Con over the weekend with his sons, Sasha and Kai.

As is typical at these events, Sasha and Kai decided to dress up for the occasion – Sasha opted for a Jedi Knight costume, while eight year-old Kai took a different approach …

… As Suicide Squad’s lead female Harley Quinn.

Liev’s been widely praised for allowing his son to go against gender norms

Others took issue with the costume – particularly Quinn’s racy get-up

Cosplaying as a female character is ONE thing. Wearing a slutty outfit of a movie character that isn’t age appropriate is ANOTHER thing!” wrote the detractor VeganMegan on Twitter.

Liev was at the event promoting his new film My Little Pony – no, really - a modern-day reboot of the classic 1980s cartoon.

He plays the Storm King in the movie, opposite Zoe Saldana, Kristin Chenoweth, Sia and Emily Blunt.

Schreiber shares custody of his sons with actress Naomi Watts. The couple split up in 2016 after an 11-year relationship.

They’ve both been very public about their commitment to co-parenting.

“We’re parents together so we’ll be together for the rest of our lives no matter,” Schreiber was quoted late last year.

Hopefully, that never changes and I don’t think it will.”
