Taylor Swift Celebrates Her Brother Austin on National Siblings Day!

Aw! Taylor Swift is such a supportive sister and she is helping promote her younger brother Austin‘s new movie.

The 28-year-old singer took to Twitter on Tuesday (April 10), which also happened to be National Siblings Day, to urge her fans to check out her bro’s new film Cover Versions.

“It’s National Siblings Day! Check out Austin‘s movie 😁,” she tweeted.

Cover Versions centers on synth-rock band Starfoxy, who, on the eve of their biggest gig ever, throw a rager that ends with a fan mysteriously dead in the pool. When the police interrogate the eccentric rockers, each one recounts very different stories in this clever murder mystery. If you missed it, check out JJJ‘s exclusive clip from the movie!
