Trisha Goddard has insisted Ant McPartlin and Declan Donnelly's bosses should stepped in and stopped them from wearing blackface on Saturday Night Takeaway.
Ant and Dec wore dark make-up and prosthetics for the skit on the entertainment show back in 2003 and have since issued a public apology.
Now Trisha has weighed in on the controversy, declaring an editor at ITV should have made sure the sketch never made it to screens.
In an interview with Mail Online, she said: "Do you genuinely think you can trick people into believing – as it was for a You've Been Framed type thing – I thought how undiverse.
"All these programs need an executive producer, a commissioning editor; there are a whole load of people it needs to go through.
"Nowhere along the line did someone go [don't do this]… because there was no one there to do that."
In a statement, Ant and Dec recently said: "During past episodes of Saturday Night Takeaway we impersonated people of colour in the undercover segment of the show.
"We realise this was wrong and want to say that we sincerely sorry to everyone that was offended.
"We purposely stopped doing this several years ago and certainly would not make these sketches today.
"We had already taken steps to ensure footage was taken down and have again recently confirmed with ITV that these segments, and any other historical content, that could cause offence, does not appear on either the ITV Hub or the Saturday Night Takeaway YouTube channel."
Former daytime TV show host Trisha previously called out comedian Leigh Francis for impersonating her using prosthetics on his show Bo Selecta! and she won a personal apology from him.
In the interview, Trisha also spoke out about the decision to pull controversial programmes amid the Black Lives Matter movement.
She declared she's glad to see the back of blackface sketches, but insisted shows such as Fawlty Towers should be left alone.
Trisha added: "The danger is knee jerk. A lot of shows that have been pulled from TV; it is knee jerk. It wasn't part of Black Lives Matter or anything like that.
"What did Fawlty Towers have to do with anything? I'm sorry but there was no black face in Fawlty Towers."
An episode of John Cleese's classic sitcom was pulled by UKTV recently because it featured racist language.
In the 1975 show titled The Germans, best known for the line "don't mention the war", long-term hotel resident Major Gowen uses the N-word repeatedly during a conversation about Indian cricketers.
However, UKTV bosses have since reinstated the episode and will now show it along with warnings bout "potentially offensive content and language".
