Former “Jersey Shore” star JWoww, whose real name is Jenni Farley, gave birth to a baby girl with fiancé Roger Mathews Sunday, E Online reported. It’s their first child.

"Jenni and Roger are so excited to welcome the newest guidette Meilani Alexandra Mathews to the world weighing seven pounds and 13 ounces," a rep for JWoww said. "Meilani and her parents are doing great and are happy and healthy. Meilani is already looking to trade her baby bottle for barbells."

MTV, the network responsible for the show that made JWoww a star, said in a statement: "We're fist pumping in celebration of Jenni 'JWoww' Farley and Roger Mathews' new baby girl Meilani Alexandra Mathews. We're so excited for the new parents and to welcome the newest member to the MTV family."

Days before the 27-year-old gave birth, the new mom shared a picture of her baby bump on her blog with the caption: "My final baby bump pic before giving birth…It better be!!! Can't wait to meet my baby girl!!"

JWoww had a tough pregnancy, she admitted on her blog. "It was the absolute hardest thing I have ever experienced!" Farley wrote in January. "I lost 9 pounds from my first appointment to [the] second! So needless to say, I was super sick and gross. I looked like hell and felt like I had a constant hangover!"

She and co-star Nicole “Snooki” Polizzi enjoyed their best friend time while both expecting baby girls.

"Jenni and I always talked about being pregnant together," Snooki, who is expecting her second child, told Us Weekly in April. "I'm so excited to go through this experience with my best friend!"
