A clip of the X Factor judge performing a sex act on MC Ultra - real name Justin Edwards - leaked last month, prompting the singer to obtain a gagging order.
"Tulisa's coming on the show to talk about the blow job," Carr told the Daily Star Sunday.
"What I found funny is that people weren't offended she did it. They were offended how bad she was."
Contostavlos recently revealed that she slept on her bathroom floor for seven days and was "devastated" when the tape leaked.
Her father Plato also confessed that the scandal almost tore his family apart, insisting that he never approved of Edwards.
Tulisa recently signed a £500,000 deal to return to The X Factor this year.
