Austin Swift's older sister may be one of the biggest pop singers in the world (you may have heard of Taylor Swift [1], yes?), but he's been slowly proving that he has a lot of star power of his own [2]. The actor stepped out in LA on Monday night to attend the premiere of Ben Affleck [3]'s new film, Live by Night, and it's kind of hard to stop staring. Austin, who plays Mayweather in the film, looked incredibly handsome when he hit the red carpet [4] in a dark suit and matching tie. While other stars like Jason Momoa [5] and Matt Damon were also in attendance [6], Austin held his own at the event. Keep reading to see more of his latest appearance, but be warned: you won't be able to stop looking into his deep blue eyes.
