When X Factor judge Tulisa Contostavlos accused contestant Misha B of bullying this weekend, debate raged on Twitter.
And it wasn't just members of the general public who got involved.
Boris Becker was one of several celebrity X Factor fans making their feelings known.
"Misha B is by far the best !!! Don't understand judge Tulisa at all !!!" wrote the tennis player.
Tamara Ecclestone also showed his displeasure over Tulisa bringing up the issue on the live show.
"I don't think it was right to go into what happens or doesn't happen backstage. What about you?" She tweeted.
It was after Misha had delivered an impressive rendition of Prince classic Purple Rain that Tulisa spoke out.
"I do have one negative this week. I think you are very competitive and I’ve seen a different side of you backstage," she said.
"In some ways you being so feisty can come across as quite mean to certain contestants and I’ve been told by a few this week there's been a few mean comments towards them.
"I’m not putting you down but take that feistiness and energy when you get on the stage and leave them all behind. Put aside the attitude."
