Courteney Cox is enjoying a "romantic" 50th birthday vacation with Johnny McDaid. The couple - who have been dating for around eight months - flew from Miami to Amanyara in Turks and Caicos on Saturday, and marked her special day on Sunday by spending the afternoon in a "secluded" part of the beach. A source said: "Courteney's birthday was Sunday and they spent all afternoon on the beach. It was just the two of them and they found a secluded spot in a cove. "It was very romantic and a beautiful setting for the afternoon. They shared a green cocktail and took a nap side by side. Courteney looked like there was nowhere else in the world she would rather be and just so happy to be doing what she was doing." According to the onlooker, 37-year-old Johnny was very attentive to his girlfriend the pair seemed "totally in love". The insider continued: "Johnny was doting on her, rubbing her leg and passing her a cold towel when she got hot. They seem very happy together and totally in love. After a long afternoon in the sun, they went back to their room for the night."
