Looks like this under-the-radar relationship has finally gone into the limelight.
Bradley Cooper made Suki Waterhouse his date for the Screen Actors Guild Awards Saturday evening, which marked the first time the American Hustle star – and former Sexiest Man Alive – has escorted his girlfriend of nearly a year to a major awards show.
Last weekend, Cooper, 39, had a different lady on his arm during the Golden Globes: his mom, Gloria.
Cooper and Waterhouse, a 22-year-old British model, have kept things pretty private in the past 10 months they have been linked together, but cozy photos of the pair make it look like these two are smitten.
Waterhouse was first seen getting friendly with Cooper last March while he was filming in Boston. The following month, the duo headed to her home continent, where they were seen romantically touring Paris via motorcycle. Apparently the City of Love enchants the couple, who were again spotted there in August with their arms around each other.
On Jan 5, Waterhouse was on the back of Cooper’s bike once again – on their shared birthday, no less – just a day after he was honored at the Palm Springs International Film Festival, according to E! Online.
She was also reportedly celebrating with the star following his Hustle ensemble win at the Critics Choice Awards Thursday.
Technically, the couple has attended an awards show before: In June, Waterhouse accompanied Cooper to the 2013 Spike TV Guys’ Choice Awards, where they were seen chatting with Hustle costar Amy Adams as well as A-listers including Mark Wahlberg and Ben Affleck. Yet the SAGs marks the first time Cooper had brought Waterhouse, who wore Andrew Gn, to a major awards show this season.
