You thought Jennifer Lawrence’s pixie cut was shocking? Take a look at the look Tom Cruise’s daughter, Bella, is sporting. Tom’s eldest daughter celebrated her 21st birthday at Disneyland this weekend, and photos from the big trip show her with a radical new look.

Bella’s brother, Connor Cruise, 18, posted a photo on Instagram that shows his older sis in the middle of an epic roller coaster ride. Bella’s arms are raised in the air, and she’s showing off a super-short buzzed look.

It’s a far cry from the shoulder-length brunette locks Bella had in this photo of herself and her superstar dad from way back in 2008. But seeing how young Suri Cruise looks in that photo, it’s clear that a lot of time has passed in the time since then.

The adopted daughter of Tom and ex-wife Nicole Kidman, Bella has been sporting a shorter hairstyle in the years since that photo was snapped. Still, this is the shortest we’ve seen her hair by far.

“Bella just really moves to the beat of her own drum," a source tells Us Weekly of the new ‘do. "This is just her way of expressing herself and showing she makes her own decisions."

Like going to Disney to celebrate her big 2-1? Because we are fully on board with that life decision. Sounds like the perfect birthday to us!
