Bradley Cooper had a very special person on hand to help celebrate American Hustle's win for Outstanding Performance by a Cast in a Motion Picture at the 2014 Screen Actors Guild Awards on Jan. 18. The actor, 38, brought girlfriend Suki Waterhouse, 22, to the big event -- their official awards show debut as a couple.
The Golden Globe nominee and the British model were photographed sitting together at L.A.'s Shrine Auditorium with the rest of Cooper's American Hustle costars. Waterhouse donned a white strapless gown with a sweetheart neckline and black accents; her beau wore a black Gucci tux.
Dating since last spring, the couple made their first formal appearance together at Cooper's American Hustle premiere in New York City in December. Waterhouse was not in attendance at last week's Golden Globes, but she did meet up with her boyfriend after the show.
"I don't talk about my boyfriend because it's boring," she explained to Elle UK of why she rarely acknowledges their relationship in public. "At least, that's what I decided to tell you when you asked. I do think whatever I say will sound weird. But the truth is, if I start talking aboiut him, I probably won't be able to stop."
