Piers Morgan has slammed Shamima Begum following her first live TV interview with the UK.
The British woman flew to the Middle East when she was just 15 to join the Islamic State and she's since expressed her regret over that decision.
The now-21-year-old has been begging for forgiveness and is hopeful she might one day be able to live in her home country again.
However, Piers Morgan said she should be let to 'rot' in Syria.
Taking to Twitter after the interview, the UK commentator wrote: "Just as well I'm not interviewing this lying, snivelling, cold-hearted, self-serving ISIS bride monster or I'd have seriously lost my temper by now.
"Begum should never be allowed back to Britain. Let her rot in the terror bed she made for herself."
He also pointed out how Begum was allowed to feely air her views on ITV, the same network he left after being criticised for his comments on Meghan Markle.
Morgan said: "Interesting times we live in when an ISIS terror bride is allowed to exercise her right to freedom of speech on Good Morning Britain but I wasn't...."
Shamima Begum claims she fully rejects the ideals of Islamic State now that she has grown up.
During the interview, she was asked by GMB host Susanna Reid why the British public should forgive her.
She told the hosts: "Because I made a mistake at a very young age, most young people don't know what they want to do with their lives. I know it's very hard for the British people to try and forgive me.
Begum explained that when she left the UK she had no idea how bad they actually were.
"I thought it was an Islamic community," she said. "I think - yes - I was groomed and taken advantage of. I did not know that there was war...
"Well, I did know there was a war, but not where women and children were living. I did not know that ISIS were trying to take over the world.
"The reason I came to Syria was not for any violent reasons, I did not want to hurt anyone in Syria or anywhere else in the world."
She also said that if ISIS were ever to come back to power in Syria and offer people a chance to rejoin or face certain death, she would rather choose death.
