I hope to god this whole kissing bullshit has been blown out of proportion and is a lie. If its true, you're right this is the end for Estelle. Michael will get off scot free while Estelle will be portrayed as the evil femme fatale stealing poor chubby Zoe's 'true love'. Ugh.
There's no way Estelle really has feelings for Michael other than simply out of boredom and Michael's just attempting to ride on her coattails. Hopefully the casual viewers will see through this but I think they are too stupid

Michael is officially my least favourite Big Brother housemate ever. What a manipulative swine. Estelle should have known better.
