Hollywood couple Nina Dobrev and boyfriend Austin Stowell continue to show just how sweet they can be. The two stars recently attended a dinner party wherein they were spotted being sweet to one another.

The former “Vampire Diaries” star and Stowell attended Eli Mizrahi's Founding Member launch dinner party held at the SKY Vault Penthouse on Tuesday night. A source told E!News that the couple looked very happy together and that they sat close to each other. The eyewitness added that Dobrev and Stowell were “acting really cute” during the dinner party.

Dobrev reportedly took her boyfriend Stowell to the Founding Member event to support Mizrahi and his new collection. The actress looked gorgeous during the party in her white crop top which she partnered with a blue blazer and matching pants. Stowell also donned a blue tailored suit to match his girlfriend’s look.

The E! source shared that the couple took “really cute photos together” with #CookieSelfie boxes available during the event. The box contained cookies which had pictures of the guest’s face on it. Mizrahi reportedly had this ordered so that party guests could take a bite out of his or her face.

Aside from the Wednesday Founding Member event, Dobrev and the “Whiplash” actor were also seen during Tuesday’s Fashion Week party. An insider told E! that Stowell was “such as gentleman” and that the actor “treats Nina with such respect."

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

Stowell and Dobrev started dating in June, as confirmed by Us Weekly sources. At the time, the two were seen getting cozy at the Hallmark Shoebox Relaunch in West Hollywood. “They looked super comfortable and happy together,” shared the insider, before adding that the pair even shared a kiss during their date.

Dobrev previously dated her “The Vampire Diaries” co-star Ian Somerhalder for three years, before they split in May 2013. Somerhalder is now married to Nikki Reed.
