The ITV2 beauty took to Instagram to share a typically racy shot with her 1.9 million followers.
Stripping down to a bright pink bikini, Caroline, 39, looked hotter than ever as she splashed about in her hotel pool.
Oozing sex appeal, the newly single starlet turned up the heat as her friend snapped away.
After soaking her long locks in the cool water, Caroline reached up and pulled her hair back behind her head.
Tilting her head to the sky, Caroline seductively opened her mouth and closed her eyes.
Risking a wardrobe malfunction, the former X Factor host squeezed her assets into a tiny bikini.
Looking like the ultimate pin-up, Caroline looked like she was about to spill out of the top at any moment.
She playfully captioned the shot: “When you drop your phone in Thailand – but you just get it fixed…”
Within minutes the post was flooded with thousands of likes and messages of adoration.
“Just wow,” one fan praised.
Another added: “Wow. Now I wished I applied to go on Love Island just to meet you.”
“Hot hot hot,” a third gushed.
Meanwhile, a fourth continued: “Caroline you looked amazing.”
