Mayim Bialik was frozen in place over new billboards promoting Ariana Grande's sexy new album cover. The 'Big Bang Theory' star wrote in a Jewish parenting magazine that she objected to sexually explicit billboards in Los Angeles and wonders what her sons are learning about women from it.

Mayim Bialik, who broke through as the title character on the TV sitcom "Blossom," says looking at the Ariana Grande billboard made her confused. The billboard is designed to look like the cover for Grande's latest album, "My Everything." Grande sits on a stool in a provocative pose grabbing for a stiletto heel.

Bialak admitted, "I have no idea who she is or what she does."

Bialik wrote: "I don't want my kids learning about sex from billboards ... Which is why a few billboards I have seen lately really bug me. There is one for Ariana Grande, and I will go ahead and admit I have no idea who she is or what she does. Based on the billboard, she sells lingerie. Or stiletto heels. Or plastic surgery because every woman over 22 wishes she has that body, I'm sure."

"Why is she in her underwear on this billboard?," Bialik wrote, "And if she has a talent (is she a singer?), then why does she have to sell herself in lingerie? I mean, I know that society is patriarchal and women are expected to be sexy and sexually available no matter what we do in society, but I guess now I need to explain that to my sons?"

Bialik already made headlines for explaining why she hates "Frozen," the highest-grossing animated film of all time, in the Jewish parenting site Kveller.

In a blog post on Kveller.com titled "Why My Sons and I Hate the Movie Frozen" confessed that she was going to "lose more fans" than when she said she was a "proud liberal Zionist during Operation Protective Edge."

The Emmy-nominated actress said she has a problem with the film's "plot and feminism," writing "Sure, it's sort of hidden, but the search for a man/love/Prince is still the reigning plot line in the movie, as it is with pretty much all movies for young people which are animated. The sister's desire to marry this guy she just met, and the other sister getting mad at her-we still have a plot about the identification of a woman being based on her desire and search to meet a man," she wrote.

"Of course, in general, in the Universe, heterosexual women tend to want to meet men and I am one of those women," she continued. "My issue is not that. My issue is that this is a movie geared to small children who I don't think need to be focusing on that as the main driving plot of a movie, especially when it's not a literary or historically-based fairy tale. And these characters are young; certainly not old enough in my socially conservative opinion to be searching for mates!"
