Big changes for JWoww!

The former “Jersey Shore” star and new mom has been sporting dark brown hair for years, but she declared on her blog that she was “trying something new and going blonde!” Jenni Farley posted Instagram photos of her new lightened look Aug. 6:

Farley, 28, gave birth to a baby girl, Meilani Alexandra, on July 13. Meilani is the first child for the “Snooki & JWoww” star and her fiance, Roger Mathews.

“Hopefully my baby still recognizes me with my new hair,” Farley tweeted on Aug. 4.
