TV presenter Kim Woodburn launched an attack on Phillip Schofield in an interview with GB News.
She called him an obnoxious and horrible man, and criticized his co-presenter Holly Willoughby for not speaking up against him.
Woodburn claimed to have had run-ins with Schofield in the past and said that he had insulted her on his show.
This comes after speculation about Schofield's future on This Morning and reports of a rift with Willoughby.
Schofield recently released a statement praising Willoughby and confirming their close friendship.
He took a break from presenting the show earlier this year when his brother was convicted of child sex offences.
Schofield has been a regular presenter on This Morning since 2002 and has presented with several co-hosts.
He and Willoughby are also the hosts of ITV's Dancing On Ice and are popular with audiences.
The pair faced criticism last year over claims that they skipped the queue for the Queen's lying in state.
Woodburn's comments have sparked further discussion about Schofield's behaviour and reputation in the industry.
