Jersey Shore: Family Vacation - Season 9

Surprise! Jenni's turning 40. Surprise, Angelina has some shocking information, and surprise, Sammi is...

Pauly and Vinny entertain crowds in Chicago, Jenni directs a new horror film, and Angelina and Sammi are holding onto a very big secret.

The gang heads to Boston to take over the iconic Fenway Park and check out a bar where everyone knows your name.

In Boston, the gang travels to the birthplace of the Chicken Tender, things get feisty between Deena and Vinny, and in Jersey - Angelina needs help.

The Guidos go back to school with an Ivy League Professor, and Angelina receives some devastating news.

As the Boston trip wraps up, the meatballs are down for the count. Plus, Mike makes a pitch, and Vinny pulls a prank.

The girls planned trip to the Hamptons takes a detour thanks to Vinny, Mike's no longer the main character, and Angelina opens up to the roommates.

The Jamptons trip is in full swing; Mike is hunting for Sammi's blessing, Angelina is chasing a fresh start, and Jenni is getting very messy.

A Jamptons house bash goes off, Mike takes "extra" to a whole new level for Sammi's Gender reveal, and Pauly gets ready to flip the script.

It's a wild Jersey summer: Mike hits beast mode, Angelina sparks up an old flame, and after all the reveals and baby showers, Sammi finally meets her baby boy.

Sammi begins life as a new mom, Ronnie is hiding something major, Mike continues to inspire… and someone slides into Jenni's DMs.

Heights are conquered, Mike turns Times Square into his own personal comeback tour, and Angelina and Vinny go another round.

Closets get cleaned, cows get involved, and Ronnie and Mike turn Vegas into a bromantic getaway.

Mike pays it forward with the opening of his rehab center, the girls shower Sammi with love before her big day, Nikki gets honest about her future and Vinny roasts the family.

The gang meets Angelina's dolls, the newest member of the family, and the countdown to the Jersey Shore Roast begins.
