The nightclub hostess was booted from the Elstree compound exactly one week after she lashed out at Blake for staying in the house at the expense of Tashie Jackson, the show's first evictee and her close friend.
"[The housemates] thought I was quite an innocent smiley little girl who didn't have an opinion and was going to make anybody's tea and wash up [without] saying anything," she told Emma Willis on Big Brother's Bit On The Side.
"I still kept a few people onside, but I think that was when it all went wrong... I am so proud of [Tashie]. She did not deserve to go in the first week."

Rebeckah added that she was so confident of being evicted that she even tried to distance herself from house lover Aden Theobald, fearing that she could ruin his chances of success.
"I kept saying to him if he was to stick with me, he's not going to make it any further down the line," she claimed.
"I knew I was never gonna win. He's got a really good chance of winning and all I wanted him to do was not constantly be with me and go off with other people. I wanted him to experience it for what it was."
Rebeckah confirmed in her post-eviction interview that she would like a romance with Aden on the outside world.
