Billie Eilish Adorably Wishes Her Brother On His Birthday

Billie Eilish expressed her love for her big brother and songwriting partner, Finneas, on his birthday as she posted some adorable throwback photos from their childhood.

Billie Eilish's latest photo on Instagram wrote a sweet message that read: "Happy birthday to my best friend. You make life feel worth something."

On the work front, the 20-year-old singer has worked with her brother on a number of songs both on the production and writing side for several artists as well as his little sister.

Their collaboration proved to be a successful one as the brother-sister duo have multiple Grammys to their name and recently made history when they bagged an Academy Award for their James Bond theme song No Time to Die.

Speaking about their journey together Billie shared, in an acceptance speech at Variety's Hitmakers brunch, that her brother was the reason for her being alive.

"Finneas is my best friend, my big brother, he’s four years older than me and we’ve been best friends forever. We started making music together when I was 13 and he was 17; he produces everything. He’s the only reason I’m anywhere in the whole world and he’s probably the only reason I’m alive," the singer added.
