"That's my hair!" Behar said, pushing the conversation about her hair during the segment.
"I was so cute", Behar said. "Joy ... are you my auntie?!"
Critics were quick to point out that NBC cut ties with host Megyn Kelly a year ago after she created a furor by suggesting that it was OK for white people to wear blackface on Halloween. She said that the hair was her own and that she had dressed as a "beautiful African woman".
"Did you have tanning lotion on, Joy?"
Behar said she'd applied some "makeup that was a little bit darker than my skin". But he confessed that on a separate occasion, he dressed as singer Michael Jackson.
In October, NBC host Megyn Kelly was canned from the network after comments concerning people dressing up as characters and celebrities of differing races on Halloween that critics decried as "racist". Behar, who usually makes headlines for squabbling with politically conservative panelists on the talk show, admitted that she was wearing makeup that was a "little bit darker" than her skin.
Needless to say, Behar's costume isn't sitting well on Twitter today. Conservative blogger Matt Walsh wrote, "Megyn Kelly was sacked from her show for asking a hypothetical question about blackface".
"Joy. Joy. Joy", she continued.
Representatives for Behar and ABC did not immediately respond to requests for comment.
Gov. Ralph Northam's shocking medical school yearbook photo of someone in blackface and another person in a Ku Klux Klan hood surfaced and, in a press conference Saturday, he admitted to wearing blackface for a dance competition. "Then, when asked about it, he justified it by saying he dressed up as "a handsome African man" and his blackface makeup "wasn't too dark"? That's exactly what Joy Behar did". One defender wrote, "Joy Behar means damn well and we should know this".
During the morning show on Thursday, Behar and the other co-hosts did not address the issue.
