Fist-pumps all around! Jenni "JWoww" Farley of "Jersey Shore" fame has given birth to a baby girl.
Farley, the body-building former denizen of Seaside Heights, welcomed daughter Meilani Alexandra Mathews on Sunday.
Her fiance, Roger Mathews, with whom she's starring in We TV's celebrity edition of "Marriage Boot Camp," made the birth announcement the same day on Twitter.
"She is here! Meilani Alexandra Mathews 7lbs 13 ounces. Words can't describe what looking into your child's eyes can do to you. Im Humbled," he wrote.
The new dad later added: "She makes cooing noises while she sleeps. Amazing how a simple little noise can make you want to make the world a better place for her 2 live."
Farley, 28, reportedly induced labor in New Jersey over the weekend, TMZ said, and she posted photos of her "lil nugget's" 3-D ultrasound on Instagram as she eagerly awaited the baby's arrival. No word yet on what inspired Meilani's tropical name.
"Jenni and Roger are so excited to welcome the newest guidette to the world," Farley's rep told E! News. "Meilani and her parents are doing great and are happy and healthy. Meilani is already looking to trade her baby bottle for barbells."
The gym enthusiasts, who announced their engagement in September 2012 after two and a half years of dating, revealed they were expecting on Christmas Day 2013. In January, they publicized that their first child would be a baby girl.
Not long after the birth, JWoww's "Jersey Shore" costars poured out their congratulations.
"I'm an auntie!!!!!" tweeted Farley's BFF and "Snooki & JWoww" costar Nicole Polizzi. "Can't wait to meet my baby."
Polizzi, 26, who is also expecting her second child (a girl), added on Facebook that she was "getting dolled up to meet my niece! So proud of my boo JWOWW."
"Congrats @JENNIWOWW and @RogerMathewsNJ on the birth of your beautiful baby girl! You are going to be the best parents! Love & many blessings!," tweeted Sammi "Sweetheart" Giancola.
"So happy for @JENNIWOWW and @RogerMathewsNJ on their beautiful baby girl congratulations!" wrote Deena Cortese.
"Congrats @JENNIWOWW and @RogerMathewsNJ . Can't wait to see the baby," tweeted Vinny Guadagnino.
