Snooki is celebrating a milestone with best friend JWoww — she took to Instagram to wish her Jersey Shore partner-in-crime a Happy 30th Birthday.

"HAPPY BIRTHDAY BOO @jwoww," Snooki captioned the pic. "We've accomplished so much together throughout the years from being fabulous hookers to fabulous moms! Through it all we've always had each others back and I'm so happy to still call you my best friend ?? LOVE YOU FOREVER!"

Jennifer "JWoww" Farley turned 30 today. She and husband Roger Matthews are parents to a one-and-a-half-year-old daughter Meilani and are expecting baby no. 2, a boy, in May.

BFF Nicole "Snooki" Polizzi, 28, is married to Jionni LaValle and has two children, Lorenzo, 3, and Giovanna, 1.
