Hot stuff ... Calista in the tub
After she was shown a montage of her time in the house, she said: "I'm so embarrassed. It makes me look like a right d**k. I knew I'd look like a bunny boiler."
She also revealed her romance with the boyfriend she was seeing when she entered the house is "completely 120 per cent off - and nothing to do with Anthony".
The petite musician looked flush as she spoke about her friendship with the boxer, complimenting him for being "sexy", but saying "he took it as if I was falling in love with him".
She said the hardest thing about being in the house was not knowing if her friends and familiy were okay, adding: "If i could just have spoken to my mum for 30 seconds."
