"I decided to rob Cougar Town -- I'm a cougar tonight, but Josh is my dear friend, so I'm not going to put my claws in him," she told E!'s Giuliana Rancic on the red carpet of Hopkins, 41.
Telling Rancic she and Hopkins go "way back," Spencer (clad in a Tadashi Soji gown, Stuart Weitzman shoes and a Judith Lieber bag) knew she had to bring him along to celebrate her Outstanding Actress in a Supporting Role win.
"To see your friend's dreams come true, there's really nothing that can make you happier," Hopkins said on the red carpet Sunday. "I've seen the blood, sweat and the tears, so she deserves this night. Maybe the world is just discovering her, but she's been a talent for a long time. To see her explode in the public consciousness like this -- them discover what I've known, her beauty and talent -- is a good time."
