Cortese says Buckner has already forged a bond with his son. “Every time he comes home, he talks to the baby,” she says. “And I feel like he’s starting to know his dad’s voice, because every time he hears it, he moves.” Baby Christopher John will be named after Buckner and Cortese’s father John Cortese, who died in 2016 after a battle with leukemia. “I get to name him after my dad and my husband,” says the mom-to-be. “It’s perfect.” For more on Cortese and Jersey Shore, pick up this week’s issue of PEOPLE, on stands Wednesday Magic Toast Photography Magic Toast Photography That’s not the only way the MTV star is honoring her late dad: On the Nov. 29 episode of Jersey Shore Family Vacation, Cortese and her costars will host a cancer charity benefit, donating the proceeds to Be The Match, the world’s largest and most diverse marrow registry. “One of the cures for leukemia is bone marrow transplant, and not many people even know about it,” Cortese says. “Be The Match is a huge donor bank, it operates around the entire world. So we thought, let’s bring awareness to that.” “I think it’s going to be nice for the fans to see us in a different light, doing something that’s for a good cause,” she adds. “And it’s something that’s close to so many of us.” Bump Love!
