Louise was shown on last night's finale episode of MIC admitting to Andy that she had spent the night at the unnamed guy's home after saying she was just going for a drink with him.
Following the show, and despite Andy agreeing to forgive and forget, Louise found herself coming under fire from angry fans - especially as it was rumoured that Louise had been with One Direction's Niall Horan.
Cast member Lucy Watson, who is dating Louise's ex-boyfriend Spencer Matthews, also appeared to brand her "selfish" in a cryptic tweet.
But despite this, Louise - who declined to comment on the whispers about Niall - ignored it all and instead shared a picture of herself sunning it up abroad.
Grow up people!— Louise Thompson (@LouiseAThompson) June 18, 2013
The photo shows the reality star floating in a giant swimming pool and she tweeted it to her fans, saying: "Winning!"
Louise didn't seem so cool, calm and collected earlier, however, as she had also posted a message saying: "Grow up people!"
Niall's reps were contacted about the rumours, yet they have not responded.
