WATCH: Mayim Bialik ‘flashes’ Piers Morgan

NEW YORK — Actress Mayim Bialik, a public advocate of her Jewish faith and modesty, showed her cleavage to Piers Morgan on a talk show.

On Monday’s Late Late Show with James Corden, the Big Bang Theory star declared herself a feminist before turning her back to the cameras and pulling down the front of her dress a bit in front of Morgan, a fellow guest.

Bialik was defending the honour of Academy Award-winning actress Susan Sarandon, whom Morgan had criticized for wearing a low-cut outfit as a presenter at the Screen Actors Guild Awards on Saturday, earning backlash on social media.

In the past, Bialik has spoken and written publicly about the challenges of maintaining faith and modesty in Hollywood.

“Being a modest dresser, that for me is a certain amount of my religious faith — privacy and chastity. Just because I have a body doesn’t mean it means to be on display,” Bialik told Fox News last year.

On JTA’s sister site Kveller, Bialik wrote in 2013: “And as a person who spends much of my life as a public person being observed, judged, and picked apart for how I look, I have come more and more to appreciate the healthy sense of protection that tznius [Jewish modesty] provides me.”

Bialik on Tuesday took to Twitter to defend herself against allegations by some social media users of sexual harassment.

 Morgan, who laughed through the semi-flashing, came to her defense.
