Alex Watson
Alex Watson almost looks more like Emma Watson than Emma Watson in this photo. Following in his older sister's footsteps, Alex landed his first modeling gig as the face for Burberry back in 2010.
Peter Nyong'o
Besides the fact that he appeared (right between Angelina Jolie and Bradley Cooper) in Ellen's most-retweeted Oscar selfie in 2014, Lupita's younger brother Peter is just a regular 23-year-old. Peter graduated from Stetson University back in May and might have also caught the acting bug, according to his sister. "He's quite the performer!" Lupita told Ellen on her show.
Joshua Alba
Jessica's hot younger brother Joshua is also an actor, appearing in CSI, Alpha Dog, and Dark Angel.
Dylan Efron
Zac Efron ignited a firestorm on Twitter in July 2015 when he shared a shirtless photo of himself along with younger brother, Dylan, leading users to praise the "Efron genes." Since then, Dylan has worked as an assistant to executive producer Ravi Mehta on 2015's Get Hard.
Austin Swift
Taylor Swift's handsome actor brother first made headlines back in February 2016 when he posted a video of himself throwing a pair of Yeezys in the trash (coinciding with Kanye West releasing "Famous" containing an explicit lyric about Taylor.) Austin has since made his on-screen debut with I.T. and Live By Night and also appeared on Still The King with Billy Ray Cyrus.
Toby Huntington-Whiteley
Damn good looks seem to run in the family. Rosie Huntington-Whiteley's hot younger brother Toby is also a model and appeared in Essence, Jon, and was the face of the 2015 Jacamo spring campaign.
James Middleton
When James Middleton isn't paling around with older sisters Pippa and Kate, he's starting his own marshmallow company. Yes, really. James is the creator of Boomf, a start-up that prints your Instagram photos on marshmallows. "When you see yourself on a marshmallow, or your loved one or your pet, you have a little moment with that little marshmallow. There aren't many products in the world like that," he told the Cut in 2014.
Hunter Johansson
You might've already seen Scarlett Johansson's twin brother, Hunter as the actress' date to the White House Correspondents' Dinner. Hunter is more into politics than acting, having worked on President Obama's campaign in 2008 and 2012.
Braison Cyrus
Miley's 23-year-old younger brother Braison is an aspiring musician and more recently a model. Braison made his runway debut for Dolce & Gabbana in June, with his proud older sister sharing the news on Instagram (albeit creating a stir for criticizing the Italian fashion house for its "politics").
Charlie Thomson
Lily James, who starred as Cinderella in the live-action Disney film, has two older handsome brothers IRL. The actress said that Charlie gave her a copy of Cinderella years before she landed the role. "Weirdly, a few Christmases ago, my big brother Charlie gave me miniature books of all the fairy stories, including 'Cinderella,'" she said.
Michael Levine
Michael Levine looks almost identical to his hunky older brother and The Voice host Adam Levine. Adam spoke out about his brother coming out in a 2011 interview, saying, "We all really wanted to provide some cushion for him and constantly let him know that's it's OK. You've gotta embrace it from the beginning."
