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.
