Life's a beach for Heather Locklear
Looking fabulous at 50, the actress spent her birthday vacationing in Hawaii with fiancé Jack Wagner
The former Melrose Place
costars were photographed strolling barefoot along the windy shoreline with their arms around each other, appearing relaxed and tan. Locklear looked spectacular
in a black bikini with a sheer black cover-up over it, while Wagner, 51, wore a bathing suit and a T-shirt.
The pair announced their engagement in August, but have not confirmed a date for the wedding. – Liz Raftery
