Nina Dobrev and Austin Stowell's relationship appears to be going strong, as the two were seen getting cozy at a New York Fashion Week party earlier this month. 

According to E! News, the actress brought the "Whiplash" actor to Eli Mizrahi's exclusive Founding Member launch dinner party at the Sky Vault Penthouse on Tuesday, Sept. 15. The "Vampire Diaries" alum was stylishly attired in a white crop top and navy blue blazer and pants, while Stowell dressed to match his girlfriend in a navy blue blazer over a blue and white checked shirt, navy trousers, and a beige tie. 

An eyewitness told E! that the two "were in attendance and sitting close and acting really cute." 

"You can tell how much they love each other just by the way they speak and their mannerisms toward one another," added the source.

The insider said that Stowell was "such a gentleman" and treated the 26-year-old with respect. 

Fashion maven Michelle Violy Harper took to her Instagram and posted a picture of the couple at the event, showing Stowell and Dobrev snacking on cookies with their faces printed on them. 

This summer, the couple was photographed being very affectionate with each other as they vacationed on a yacht in the South of France. The two were also seen in New York City earlier this year, as Dobrev reportedly visited Stowell on the set of his new show, "Public Morals." 

Although the two have yet to talk about their relationship, it's clear that the actress supports Stowell in his acting career. She has even promoted his show on Instagram, uploading a promo picture for the TNT series last month with the caption: "Only a few hours before the premiere tonight!!!"

Some of her Instagram followers were confused by the post, thinking that Dobrev was going to be on the show, but one commenter clarified, "She's not in the series, her boyfriend is." 

The star may have also put together a viewing party for the premiere of the new series as she posted a picture of her with Stowell and a few of their friends and captioned it, "So excited to watch the goofball in the Yankees hat kill it in Public Morals tonight!!! 10pm."
