Olly Murs' nan banned him from performing his track 'I Don't Love You Too'.
The 'Wrapped Up' hitmaker revealed his grandma, Eileen, was not impressed with a track which the star wrote about her and her husband's arguments, requesting for her grandson stopped singing the song at his shows.
He said: "I wrote a song on my second album and it's called 'I Don't Love You Too'. It's about two people having an argument - it was about my nan and grandad.
"She'd be the first to admit that they do argue. She says: 'I hate you Stan,' and then she says 'I don't mean it.'"
Despite confessing she does row with Olly's grandad, the 30-year-old singer confessed "she didn't like it".
He explained: "I didn't sing it on tour because I didn't want her to be upset watching it. I decided to cut that from the set."
The star - who released his fourth studio album 'Never Been Better' last month - said his grandmother would probably still be getting angry if she comes to see him in concert though, because she gets jealous of other women showing affection towards him.
He told the Sunday Mirror newspaper: "I get a lot of nans who like me.
"My nan gets very jealous if she sees anyone come up and kiss me. She says, 'He's my grandson, not yours'."
