40+ Celeb Siblings Where We Can't Even Think of One Without Mentioning the Other, and What They Looked Like Growing Up

There are loads of celebrity siblings in the entertainment world. In fact, many of these celeb siblings come as a pair. Join us as we take a look at some throwback photos of these famous siblings growing up.

It’s always worth pointing out that Willow and Jaden Smith have inverted versions of their famous parents’ names. That is, daughter Willow is named after her father, actor Will Smith. And son Jaden is named after his mom, actress Jada Pinkett Smith. Anyway, Jaden is an actor and rapper, and Willow a singer-songwriter.

Aren’t they just adorable? This is a family snap of the Smith kids when they were tiny tots. Willow was born in 2000, while older brother Jaden was born two years earlier. These two also have an elder half-brother from Will Smith’s first marriage to Sheree Zampino. When they were still small, Willow and Jade each acted in movies with their dad. Later, Willow voiced an animated character in a movie with her mom. They were always bound for showbiz!

Nowadays, American singer-songwriter Billie Eilish is a bonafide star. The multi-Grammy award winner often performs alongside her brother, Finneas O'Connell. The talented siblings collaborate on music, with Finneas writing her debut single, “Ocean Eyes.” Impressively, Finneas is a Grammy award winner in his own right. As well as working with his little sister, he has written and produced for Halsey, Camila Cabello, and Justin Bieber. He’s also released his own music and done some acting. This is one pair of super cool siblings.

There’s a reason these two grew up to be so talented! And that reason is named Maggie Baird (and maybe their dad, Patrick O’Connell too). Billie and Finneas’ mom, Maggie, is an actress and screenwriter. She homeschooled her kids so they could spend time together and have the freedom to learn. This meant that little Billie and Finneas were making music when they were small children. The reason these celebrity siblings have different surnames is that Billie uses her middle name, Eilish, as her stage name.
