Nina Dobrev has sparked dating rumors with Austin Stowell. The duo reportedly "looked so into each other" and "kissed" when attending the Hallmark Shoebox relaunch at The Improv in Hollywood on Wednesday, June 10.

"[Nina] walked in with a few people including her new man [Austin]," a source told HollywoodLife, "They stayed for the first comic and kissed three times while the performance happened! She was very affectionate with him and she was with other friends as well and she wasn't afraid of being intimate around friends."

An onlooker told PEOPLE that "The Vampire Diaries" alum and the "Whiplash" star "were glued together the entire night, laughing and getting cozy during the comedy show." Another source added, "She was very happy to have a night out with her new guy. And she was very excited to see her friend Rob Riggle host the show."

This isn't the first time Nina and Austin have been spotted together. Back in May, they both attended Indie 500 and a dinner with fans who won for a Kind Campaign fundraising initiative. During the dinner, Nina and Austin sat side-by-side.
