For Jared Leto, Sunday night’s Academy Awards was a family affair. The actor and singer-songwriter, who picked up a Best Supporting Actor Oscar for “Dallas Buyers Club,” in which he played an HIV-positive transgender woman named Rayon, was accompanied to the Dolby Theater by his mother Constance and his brother Shannon.

During the 42-year-old Louisiana native’s acceptance speech, Leto thanked his mother for “teaching me to dream” and added: “To my brother Shannon, the best big brother in the world, you’re a true artist. Thank you so much for sharing this insane and amazing adventure.”

Many music fans will recognize Shannon Leto as one-third of the band 30 Seconds to Mars. Shannon Leto, 43, distinguished by his strangely pointed eyebrows – which many Twitter users took to social media to express either admiration or incredulity over – is a drummer who plays alongside his brother, the band’s guitarist and lead vocalist.

Shannon and Jared Leto formed the band in 1998 and released their eponymous debut album in 2002. Like his Oscar-winning brother, Shannon Leto was born in Bossier City, La. The duo has been playing music together since childhood.  

“I think your past shapes you, your past can either hold you hostage or it can set you free,” Shannon Leto told NBC Latino in a 2013 interview. “But either way you are going to learn from it; it’s part of your makeup, what you decide to do with all that information is up to you. … You have to work hard, you can’t just think about it or talk about it with friends; you have to do it and be willing to sacrifice a lot.”
