Taylor Swift and Blake Lively are standing with Miles Teller.

Fans of the 31-year-old pop star recently railed against Teller after he starred in her music video, "I Bet You Think About Me," directed by Lively.

After the video was released, fans took to social media to speculate about whether Teller, 34, is vaccinated against coronavirus and whether he could have put Swift, Lively and others involved with the project in danger. The speculation follows alleged rumors earlier this year that he was not. 

However, at the time, his rep denied it to the Daily Mail, stating: "Your facts are incorrect." And on Tuesday, Teller tweeted that he is "vaccinated and have been for a while."

"isn't miles teller anti-vax? why is he in the new @taylorswift13 music video…" tweeted a viewer.

Added another: "Lemme get this straight… Out of every employable actor in the business, Taylor Swift and Blake Lively decided that during the pandemic they’d hire literal anti vaxxer Miles Teller to star in their new video? Miss girls this ain’t it… No."

Teller himself cleared up rumors of not only his vaccination status, but seemingly also his stance on vaccines in general.

"Hey guys, I don't usually feel the need to address rumors on here but I am vaccinated and have been for a while," he tweeted on Tuesday, per Insider. "The only thing I'm anti is hate."

It seems the message has since been deleted. Fox News has reached out to a rep for Teller.

Meanwhile, Swift and Lively, 34, shared messages of appreciation to Teller and his wife for appearing in the video. 

"So grateful to Miles for being the greatest dance partner and friend to me," Swift wrote on social media alongside several photos from the video shoot. 

She then offered up some praise for Teller's wife, Keleigh, who also appeared in the clip.
