Viewers were horrified when the 'Celebrity Big Brother' star flashed her breasts at housemate Saira Khan during a row but 'Geordie Shore' co-star Charlotte - who previously won the Channel 5 reality show in 2013 - took to Twitter to insist Marnie is not a bully.

She tweeted: "Aw Marns wish you hadn't done that.

"I honestly think that @MarnieGShore was just caught up in the game and a little bit drunk. She's defo not a bully.

"Tomorrows ep I'm more then certain we will see her apologise when she realises (sic)."

Marnie's flashing was part of a Truth or Dare game in the house and she approached 'Loose Women' star Saira following an earlier row in which she called Saira "judgemental" and "opinionated".

She said: "I feel like I just need to say sorry to you.

"I just want to ask you a very serious question. Do you think that we had the big confrontation because I've got better boobs than you?"

Then Marnie proceeded to pull down her top and shook her breasts at Saira, who was visibly uncomfortable.

Following the controversy, a message was posted on Marnie's Twitter account, which said: "Haven't we all done something silly in a game of truth or dare? Calm down with the hate! (sic)."

Meanwhile, fellow housemate James Whale told Marnie her actions were "unnecessary", but Saira insisted she "wasn't bothered".

However, earlier in the day Saira broke down in the Diary Room after clashing with Heavy D, Lewis Bloor and Stephen Bear.

She sobbed: "I'm so out of my comfort zone with some of these people. I did not think 'Big Brother' would make me crack after three days.

"I'm trying to get to know people and no one has gotten to know me. I really do not like Bear."
