Her precious angel has arrived! Jenni "JWoww" Farley gave birth to her first child, a baby girl named Meilani Alexandra Mathews, on Sunday, July 13, Us Weekly can confirm.

"Jenni and Roger are so excited to welcome the newest guidette Meilani Alexandra Mathews to the world weighing 7lbs and 13 ounces," JWoww's rep tells Us Weekly. "Meilani and her parents are doing great and are happy and healthy. Meilani is already looking to trade her baby bottle for barbells.”

Engaged to beau Roger Mathews since September 2012, the 28-year-old Jersey Shore alum documented her pregnancy on social media leading up to her daughter's birth. Just days before welcoming her little mini-me, 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!!"

Farley got her start on MTV's Jersey Shore before starring on the spin-off series with pal Snooki.

"We’re fist pumping in celebration of  Jenni 'JWOWW' Farley and Roger Mathews’ new baby girl Meilani Alexandra Mathews," a rep for MTV told Us in a statement. "We’re so excited for the new parents and to welcome the newest member to the MTV family."

Farley also enjoyed spending time with pregnant BFF Nicole "Snooki" Polizzi during her pregnancy. "Jenni and I always talked about being pregnant together," Snooki, who is expecting her second child, told Us in April. "I'm so excited to go through this experience with my best friend!"

Pregnancy wasn't exactly a walk in the park for Jwoww, however. The reality star admitted on her blog she had a rough first couple of months. "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!"
