As the Jersey Shore cast prepares to reunite for Jersey Shore: Family Vacation, Ronnie Ortiz-Magro is preparing for some big changes to his own little family, revealing last month that he has a baby on the way with girlfriend Jen Harley. The reality star also just shared the sex of the baby, and his reaction to the reveal is priceless.

“This is the face you make when pink feathers come out of the popped ballon, instead of blue!” Ortiz-Magro captioned the pic of the moment he and Harley learned they’d be having a girl during a party at the PKWY Tavern in Las Vegas, Nevada. The first-time father-to-be looked a little shocked, to say the least.

Ortiz-Magro used a series of jokey hashtags to further express how nervous he was to welcome a little girl to the world, including “#WaitWhat” and “#AMillionThingsWentThroughMyHead.”

Harley spoke for the both of them in her own Instagram caption, writing, “If you can’t tell, we’re beyond excited for this baby girl,” alongside a pic of Ortiz-Margo kissing her belly while she held a pink balloon. “@realronniemargo you’re going to be such a good daddy I love u!”

While Harley is already the mom of an 11-year-old son, Ortiz-Magro previously said that he sought newborn advice from his new-parent Jersey Shore castmates. “They all went through different experiences, which was great,” he told Us Weekly.

Congrats to the expectant parents!
