It claimed James was bored of interviewing pop stars, and that he was fed up with being "told off" by the show's bosses.
But James says he had nothing to do with the article - and that he loved doing the programme and got on really well with the other presenters.
He added that after the last show on Saturday, one of the SM:tv bosses gave him a big hug and told him things were going well.
What do the bosses think?
Conor McAnally, an executive producer on the show, said there was no way James could keep working on the show, and said that they'd be looking for a replacement.
They're also looking for a replacement for Cat, who's also leaving SM:tv.
It tops a bad six months for the Saturday morning show - which has slipped in the ratings since losing Ant and Dec last year.
