A source tells E! News, "Bradley and Suki are very much a couple," regardless of the speculation that the two have broken up.
The British model was seen arriving at LAX by herself over the weekend in a pair of gray sweatpants and a green sweatshirt.
The blond beauty carried her handbag, coat and iPad as she strolled through the arrivals terminal.
The last time that the couple was spotted together was at the Academy Awards, where Cooper was nominated for his work in American Hustle.
B.Coop's girlfriend looked radiant in a metallic Marchesa one-shoulder gown and couldn't keep her hands off of her leading man.
"I had such a great time," she told E! News as she made her way into the Governors Ball after-party in the Ray Dolby Ballroom. "I loved it. It was a lot of fun."
Just two weeks before they stepped out for the biggest night of the year in Hollywood, the loved-up duo attended a dinner at the White House.
The 39-year-old hunky star looked handsome as ever in a perfectly fitting tuxedo, while his ladylove looked appropriately chic in a Marios Schwab dress and blazer.
But Bradley and Suki weren't the only stars in attendance at the fete, held in honor of visiting French President Francois Hollande. Mindy Kaling, Julia Louis-Dreyfus,Stephen Colbert and J.J. Abrams were on hand as well.
