Taylor Swift's handsome brother Austin Swift is now a movie star, the singer announced the news on her Instagram account.

“My brother @austinkingsleyswift just acted in his first movie and I'm all proud and stuff,” Swift wrote on Instagram, along with a photo of his brother from what looked like one of the scenes from the movie. The picture shows Austin driving a car, wearing an unbuttoned white shirt with lose necktie hanging around it.

According to E! News, Austin is starring in a movie titled, “I.T.,” alongside Pierce Brosnan, Anna Friel and Stefanie Scott. Disney star Scott plays Brosnan's daughter, who is stalked by someone from the technology field.

The IMDb page of this John Moore-directed movie shows it as “under production.” Austin plays the character of Lance in the film, the page said, adding that the movie has a theme of “crime, drama and mystery.”

Brosnan both stars in and produces “I.T.,” where he plays a businessman, who comes to loggerheads with a young IT consultant to discover that he is using technology to threaten his personal and professional life. No release date is announced for the film yet, Deadline reported.

Swift is close to her younger brother and even attended his graduation ceremony at the University of Notre Dame in May. She later took Austin to Las Vegas, where he partied with many celebrities and posted the picture on his Twitter account. The picture shows Austin having fun with Ed Sheeran, Swift's rumored boyfriend Calvin Harris and One Direction's Louis Tomlinson and Niall Horan.

Austin, 22, is not very active on social media as his last post on Twitter dates back to Aug. 16, approximately the same time when he last updated his Instagram. According to a fan website of Swift, Austin was also a freelance photographer for Getty images and “some of his photographs of Taylor appear in publications like People magazine and Rolling stone Magazine.”
