"The Jersey Shore's" dynamic duo is back for the fourth and final season of "Snooki & JWoww."

Nicole "Snooki" Polizzi, 26, and Jenni "JWoww" Farley, 28, the beloved guidettes, will trigger viewers' emotions as we watch the celebrations of important milestones in their lives.

The trailer, released earlier in October, revealed that the show will feature "two babies, one wedding," according to NJ.com.

There will be crying (not only from the newborns), yelling, singing, dancing, laughing, and a whole lot of love. You know, the usual.

The 12-episode series (too short, IMO) will chronicle both Snooki and JWoww's simultaneous pregnancies, and neither one of them will be shy about their personal issues in front of the camera...but we know that already.   

Polizzi and fiancé, Jionni LaValle, 27, previously welcomed their son, Lorenzo, now 2, in August 2012 (the same year as their engagement), and season four will introduce us to their newborn baby girl, Giovanna Marie, who was born in September of this year.

Farley and fiancé, Roger Mathews, 37, will welcome their first-born on the show as well. Meilani Alexandra, their baby girl, was born in July 2014.

Viewers will have an inside look at both delivery rooms as Snooki and JWoww bring their babies into the world, according to Hollywood Life. Don't worry, not too much of an inside look.

Babies aren't the only excitement for this season. Snooki will marry her longtime love, Jionni, before the end of the series. The couple is set to wed at the Venetian in Garfield, New Jersey, NJ.com reported.

Tune in to watch best friends (and neighbors) Snooki and JWoww help one another with the demanding and rewarding duties of motherhood.

Ladies and gentlemen, they've ditched their tequila shots for formula bottles.

Season four of "Snooki & JWoww" premieres on November 5, at 10p.m. on MTV.
