The former Strictly Come Dancing professional certainly didn't hold back as he tuned into tonight's instalment of the reality series.
During the latest episode, Chloe Ferry could be seen cavorting around the garden in a tiny pink bikini while James Cosmo sat in the smoking area.
The Geordie Shore star asked him: "Have you ever been to Ibiza? I feel like I'm in Ibiza sunbathing in my bikini."
She then proceeded to jump around in the swimming pool, with her struggling to contain her ample assets in the metallic two-piece.

The Game of Thrones star could not have been less impressed as he watched on in shock. He shook his head before getting up and walking back in the Borehamwood Bungalow.
And, it seems his baffled facial expression entertained those at home, including former housemate James.
The dancer slammed Chloe on Twitter, writing: "I love the look of total disgust on James C's face when looking at Chloe… @bbuk #CBB Her parents must be so proud."
Viewers at home were also entertained by James' face, with one tweeting: "James pulling a face at Chloe so we don't have to. #CBB."
