Nina Dobrev and Austin Stowell started dating earlier this summer, and the two have been photographed several times throughout the year. They went on a yacht vacation in the South of France and were also spotted together at various events. But this Sunday, the pair made their red carpet debut as a couple at the premiere of "Bridge of Spies." Dobrev was there to support her boyfriend, who has a role in the film.

The "Vampire Diaries" alum wore a black dress with a red side panel and black heels for the event, while Stowell looked dapper in a dark suit and tie. The couple looked happy as they posed for the cameras, with Stowell's arm around her waist.

The couple was first rumored to be dating after they were seen together at a comedy bar last July.

The two also attended Jaime King's baby shower together. They also were spotted at a charity dinner together, and during their South of France vacation this summer, the two were seen being very affectionate with each other as they rode jet skis and spent time relaxing on the yacht.

A source who was at Eli Mizrahi's Founding Member dinner launch party at New York Fashion Week last month told E! News that the couple's relationship appears to be going strong. "You can tell how much they love each other just by the way they speak and their mannerisms toward one another. Austin is such a gentleman and treats Nina with such respect," the source said.

Though both actors are busy with their respective careers, the two obviously take time to be there to support one another. Both Stowell and Dobrev will be starring in several films in the coming months. Aside from "Bridge of Spies," Stowell will be starring in "In Dubious Battle" and "The Long Home," while Dobrev has been cast in the upcoming film "Arrivals" with "Game of Thrones" star Maisie Williams.
