Newlyweds Katharine McPhee and Nick Cokas are spending their honeymoon on the Hawaiian island of Oahu.

The 23-year-old singer-actress and producer Cokas, 42, were married on Saturday in Beverly Hills before heading to the tropical getaway of Oahu. Romance wasn’t the only thing on McPhee’s mind as she was spotted shopping at the local Gucci store – but they couple did stop for a post-purchase hug.

McPhee and Cokas married last Saturday in Los Angeles before friends and family.  The two announced their engagement back in November.
