Jersey Shore's Ronnie Ortiz-Magro will have to hold off on "GTL" for now and grab some diapers as he's now officially a dad.

On Tuesday, April 3, E! News confirmed that the reality star and his girlfriend, Jen Harley, welcomed their first child together, a baby girl. This is the second child for Harley as she already has an 11-year-old son, Mason, from a previous relationship.

A source close to Ortiz-Magro stated that he's beyond elated to be a father.

"He's over the moon," the source stated.

From G-T-L To Fatherhood

In December 2017, during an exclusive interview with Us Weekly, Ortiz-Magro and Harley announced her pregnancy and revealed that they were expecting a girl.

The first-time dad also shared the news with fans via Instagram. The Jersey Shore alum posted a photo of himself and Harley as he holds her growing belly.

"Thank you to everyone who has been supportive with advice and encouragement. People keep saying becoming a parent is the part of life. I've been blessed enough to have SOO MANY best parts of life," the 32-year-old captioned the photo.

After disclosing the news with his fans, the pair continued to document their moments to parenthood. In January, Harley shared photos from their gender reveal party on Instagram.

"If you can't tell we're beyond excited for this baby girl. Thank you to my bff fir setting up the reveal party. You guys are amazing. @realronniemagro your going to be such a good daddy I love u!" the Harley labeled the shots.

Luckily, Oritz-Magro has nothing to worry about when it comes to seeking parenting advice as his co-stars, Nicole "Snooki" Polizzi, Jenni "JWoww" Farley, and Paul "Pauly D" DelVecchio are all parents to daughters. 

The couple's daughter came at the perfect time as Ortiz-Magro just finished wrapping up filming for Jersey Shore Family Vacation, which is set to premiere on Thursday, April 5, at 8 p.m.
