However, the younger sister of Kylie Minogue did cut Lindsay some slack – explaining that the mean Girls star had brushed up on her knowledge of Aussie celebs before the TV show began.
“But Lindsay studied really hard. She came up with some great guesses,” Dannii continued.
“She's generated enough column inches and interest about the show to get people interested enough to watch.”
Dannii’s defence of her fellow judge comes after Lindsay denied reports last week that she was set to be replaced on the second season of the Ten show.
Speaking to The Daily Telegraph’s Confidential, media analyst Peter Cox said the American actress “lacked local knowledge.”
“I think it looks silly for the show and lowers the credibility of it. I don't think she contributes anything to the show and she lacks local knowledge,” he said.
“She's not able to guess who the right person is, not that it's easy, but she keeps putting up LA people who couldn't possibly be on the show.”
Cox’s comments follow confirmation from Channel Ten's chief content officer Beverley McGarvey last week that all four judges – Dave Hughes, Jackie O, Dannii Minogue and Lindsay Lohan – will all return for the second season.
