Popsugar Celebrity Award Season Funny Reactions to Beanie Feldstein & Jonah Hill as Siblings 17 People Who JUST Realised Jonah Hill and Beanie Feldstein Are Siblings 6 January 2020 by Amanda Prahl Image Source: Getty / Kevin Winter Hollywood siblings are usually easy to spot, but it turns out there's one duo not a lot of people knew about: Beanie Feldstein and Jonah Hill. Yep, that's right: the Booksmart star is Jonah's younger sister (10 years younger, to be exact). It's easy to have overlooked their relationship for the simple reason that they don't share a last name, since Jonah uses his middle name as his last name for professional purposes, while Beanie uses their "real" last name. While arriving for the Golden Globes — where Beanie is nominated for her role in Booksmart — she shared her excitement over her brother's recent engagement, calling him "my best friend in the world" while talking to Us Weekly. If you didn't know they were related, you're definitely not alone. Ahead, check out the reactions from fans who are just learning about this talented sibling duo now!
