#oops! Nina Dobrev and Austin Stowell are dating, but weren’t following each other on Twitter

File this one under #millennialproblems: Nina Dobrev and her new beau, Austin Stowell, are dating, but the pair only recently -- and publicly -- acknowledged that they weren’t following each other on social media.

That’s totally a big romantic no-no these days, right?

Stowell, 30, who made his relationship with former “The Vampire Diaries� star red carpet official at the premiere of his latest project, Steven Spielberg’s “Bridge of Spies,� earlier this month, took to Twitter on Tuesday to admit his relationship faux pas.

“That weird moment when you realize you don’t follow your girlfriend on Twitter #socialmediaproblems,� the “Secret Life of an American Teenager� alum tweeted, sharing a screenshot of the brunet beauty’s profile page. The “Public Morals� actor later posted a screenshot to prove the follow was official.

But Stowell wasn’t the only one who had neglected to hit the “Follow� button.

“That awkward moment when u realize ur not following him either&gotta do it realfast b4 he realizes,� Dobrev, 26, responded.

According to People, the couple sparked up their romance in June when they were spotted together at a comedy show in Hollywood, then hit St. Tropez together. The “Degrassi: The Next Generation� actress was notably linked to her “TVD� costar Ian Somerhalder for three years.
