Although they might not all be famous or star in major blockbusters, these younger brothers of famous celebrities deserve just as much attention as their famous siblings, if not more so.
From well-known ones like Zac Efron's brother Dylan, to the not-so-well-knowns like Rachel McAdams' brother Daniel, these little bros are so hot, you'll wonder how you never knew they existed.

When you have an older sibling who's famous, growing up in their shadow should be hard, right? Not according to Austin Swift, whose older sister is none other than country superstar Taylor Swift.
“When we were kids, I saw Taylor write songs every day for years when there was no one to play them to,” he said back in 2016.
He credits Taylor's hard work and determination for being his motivation for success now that he's an adult.
"I remember watching her go door-to-door dropping off demo CD's at labels that never called. She was there when she was performing at karaoke contests and in the corners of parties with the same enthusiasm she now plays to stadiums full of her fans," he said. "Having seen that example, how much goes in, how long it took … That's always going to be bedrock for who I am and who I want to be."
A graduate of University of Notre Dame where he studied film editing, it looks like that Swift drive is paying off. He was cast in the movie I.T. alongside Pierce Brosnan in 2016 and Live by Night with Ben Affleck that same year. With Taylor on hiatus, it looks like it's her brother's turn to be in the limelight!
