GMTV presenter Kate Garraway has been told off by show bosses for accusing Mariah Carey of being a diva.

In her weekly magazine column Kate blasted Carey for bringing her own toilet paper to the studio and for having her minders carry her to a chair. However The Mirror has claimed that Garraway wasn’t even in the studio when Mariah Carey was interviewed and that her comments were a gross exaggeration of actual events.

A source said: “What Kate claimed wasn’t true and it has caused big problems backstage. The huge entourage was actually a choir and musicians used by Mariah.

“When stars come to be interviewed on GMTV they don’t expect this. Even worse, what Kate wrote wasn’t true.

“Kate has been carpeted by bosses and told it cannot happen again. It looks bad for GMTV to be linked to these sort of comments about a guest.”

A source close to Garraway added: “She was misinformed and is mortified by what has happened. She has apologised to Mariah and her bosses and will make amends in her column next week.”
