From long brown hair to crimped curls, you never know what hairstyle Serena Williams will wear next.

Recently the tennis star ditched her straight hair in favor of her 34th birthday. Williams posted an Instagram photo of herself on with natural curls with the caption: “Goodbye 33! Hellooooo 30fun!!!!” Although we love her straight hair looks (who could forget that amazing NY Magazine cover?!) we’re also loving her natural curls that prove once again, that 2015 has still been a great year for her.

Which hairstyle of hers is your favorite?
