AceShowbiz - Last week, Keke Palmer went viral after she confessed to not knowing who Dick Cheney was when taking a lie-detector test with Vanity Fair. Now, the actress has set the record straight during a panel at the Brooklyn Expo Center, revealing that she's now familiar with the former vice president, and it's all thanks to her mom.

Speaking to the audience, Keke said that her mom was among those who couldn't believe that her daughter didn't know who Cheney is. "It was so crazy, my mom was like, 'You didn't know who Dick Cheney is?' " she recalled, adding that her mom started teaching her after that. "Then she tried to tell me what he was about and I said, 'I see why we don't talk about him!' "

She continued, "Geez Louise! I truly did not know who the man was. God bless him, though."

Keke generated a new meme after her lie-detector test video went viral. During the test, the "Hustlers" star was asked if her "True Jackson" titular character was a better vice president than Cheney. She was also shown a picture of the politician, but she looked clearly confused after seeing the picture. Rather than lying, Keke opted to be honest and said, "I hate to say it. I hope I don't sound ridiculous. I don't know who this man is. I mean, he could be walking down the street, and I wouldn't know a thing."

She then pushed the picture of Cheney away with a pitiful look in her face while saying, "Sorry to this man."

Her comments quickly became a hot topic on social media, with many making memes out of it. Using a clip of Keke saying the viral "Sorry to this man," phrase, one wrote, "Drew Barrymore in 50 first dates:" One other joked, " 'I don't know her' passing the baton to 'Sorry to this man,' " referencing to a popular clip of Mariah Carey saying, "I don't know her," when she was asked about Jennifer Lopez.
