Morgan described Boyle as "incredibly sweet"
Piers Morgan has defended Britain's Got Talent star Susan Boyle over claims she lost her temper at a London hotel.
The singer is said to have sworn in the lobby of the Wembley Plaza Hotel after being "wound up" by two strangers.
But speaking on LBC 97.3, Morgan said Boyle has been in "floods of tears" and is suffering from "crippling" nerves.
Saxophonist Julian Smith won Thursday night's semi-final public vote, while grandfather and granddaughter duo Two Grand was saved by the judges vote.
They will join Susan Boyle and the other contestants who have made it onto the grand final of the ITV1 show on Saturday night.
Earlier, Morgan described 48-year-old Boyle as "an incredibly sweet, nice, gentle person".
According to reports, the finalist lost her temper on Wednesday, before police stationed at the hotel in north London intervened in the situation.
She was also said to have sworn at a television set in the hotel bar after Britain's Got Talent judge Morgan praised her 12-year-old rival, singer Shaheen Jafargholi.
A spokesman for Boyle said: "The police were escorting a journalist from the premises who had been winding Susan up.
"Susan and her sister were talking to the police telling them what had happened."
Morgan told radio host Nick Ferrari the singer has been struggling to cope with her sudden fame, which has seen her first audition downloaded an estimated 100 million times.
He said: "Anybody who has gone through that incredible transformation is going to be feeling the most unbelievable pressure."
Morgan added: "The final is on Saturday and she knows that everything may rest on that one performance. You could see the nerves almost crippling her on the semi-final show.
"I just think it's time that everyone slightly backed off."
