Katharine McPhee and David Foster rang in his 69th birthday in style on Thursday with a day full of fun activities and plenty of PDA to go along with it. The pair first stepped out for a lunch date to celebrate the occasion, before heading attending the annual star-studded Friends of the Israel Defense Forces (FIDF) Western Region Gala in Beverly Hills in the evening, which raised $60 million to support the brave men and women of the IDF. McPhee, 34, stunned in a black zip-up leather dress, while Foster looked dapper in a dark-colored suit with a white shirt and black tie. In between posing for pictures, chatting to guests and listening to surprise guest performer Pharrell Williams, the pair made sure to show their affection.
