Piers Morgan was forced to apologise on today's Good Morning Britain after Sinead O'Connor swore live on air.
On Monday's edition of the daytime show, the presenter and co-star Susanna Reid were talking to the singer about her comeback.
But it seems Sinead appeared to forget where she was and dropped the b-word during the chat.
Speaking about her own love life, Sinead admitted she's happier when she's single.
Sinead then said her friends joke about making a break-up song titled: "Nothing Compares 2 U, you [bleep]".
Piers immediately jumped in, saying: "We would obviously like to apologise for that."
He told Sinead: "Sinead, you're on breakfast telly you can't say things like that."
Susanna exclaimed: "But she's Sinead O'Connor!"
Piers added: "We're very, very, civialised on this programme! If it falls to me to get Sinead O'Connor to behave herself, then so be it."
Sinead, you're on breakfast telly you can't say things like that.
Sinead said: "It's never going to happen."
Meanwhile, during the interview, Sinead spoke about converting to Islam in 2018 and changing her name to Shuhada Davitt.
She said on the show: "As soon as I read chapter 2 of the Quran, I was like, oh my god I've been a Muslim my whole life and didn't even know it.
"In Islam you don't call it conversion, you call it reversion, the idea is you were born Muslim in the first place, any person with any logic would see they were Muslim all along. So that's actually what happened to me."
Speaking about the reaction from other Muslims, she said: "Very nice reaction. Muslims are lovely people, Muslims are very tender and very loving people, despite what anyone may think. You're a sister."
However, she admitted she has been the subject of prejudice from others, explaining: "Oh yeah, it makes me laugh. It actually makes me laugh. I suppose I'm used to it as a woman, and as a bit of a controversial woman, I'm used to putting up with abuse.
"In a strange way it makes me proud, I can't really explain why, if somebody hates me because I'm a Muslim I stand up a bit taller actually. It did at first make me angry."
