The couple were photographed in just their swimming things on the balcony of their villa in Camps Bay. In one pic, Derek, 26, is seen climbing on top of Cheryl for a cuddle. She then appears to be whispering sweet nothings in his ear before he rubs sun cream on her body.
"Derek and Cheryl are more than just pals. They have done everything they can to keep their relationship a secret, but it has become more and more difficult," the Sun quoted a source as saying.
