People can say what they want about Nicole "Snooki" Polizzi's pregnancy news
, but Deena Cortese says her BFF will be a natural at raising a baby with fiancé Jionni LaValle
"I think Nicole is going to be a great mom," Cortese, 25, told Ryan Seacrest
Friday on his KIIS-FM
morning show. "She's a very genuine person and her heart's always in the right place. She always puts people before her."
Even though Polizzi, 24, has a reputation for being a party girl
, Cortese says her pal has always imagined starting a family in her future.
"This has been her dream – getting married, having kids," she explains. "She's really happy and I'm really happy for her. She's going to love that little meatball."
Cortese is on-board when it comes to helping care for the little one.
"I'm going to spoil that little guy," she says, after Seacrest refers to her as "Aunt Deena."
But even though she's overjoyed about her Jersey Shore
sidekick's news, Cortese, who doesn't know the gender of Polizzi's baby yet, says, "I'm going to miss my little partner-in-crime."
