Courteney Cox showed love for her boyfriend, Johnny McDaid, in the sweetest PDA-filled birthday tribute. The Friends alum, 61, shared a series of photos via Instagram to celebrate the singer-songwriter's big day on Thursday, July 24. "Happy Birthday J. You mean so much to so many, but you mean everything to me. I love you ," Cox captioned the heartfelt post. In one photo, McDaid adorably held Cox close to his chest with his arms wrapped around her. She beamed from ear to ear as they stood on a waterfront balcony.
