On Friday, "Big Bang Theory" actress Mayim Bialik slammed Ariana Grande in a recent blog entry that she published on Kveller.com, E! News reports.

After admitting to not knowing who Ariana Grande is or what she does, the mother of two slammed the pint-sized star's sexualized appearance on billboards as being inappropriate for her two sons.

"A few billboards I have seen lately really bug me," Bialik began her blog post. "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."

Bialik continued her entry by questioning Grande's choice to wear lingerie in the racy billboard ad.

"Why is she in her underwear on this billboard though? 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?"

In addition to Grande, Bialik also took aim at Levi's and "Masters of Sex" billboard ads. [E! News]

"Then there are the Masters of Sex ads. Seriously? How am I supposed to explain those to my kids? Especially my older son who can read?" she wrote, followed by, ""And while I'm having an old lady moment, what's up with those ads for Levi's jeans where it's basically people groping each other as foreplay and undressing each other while making outt? Just tearing those jeans off of each other's bodies like it's the last day to repopulate the earth."
