Jamie Presley can't believe she's having twins!

Jamie Presley couldn't believe the news when she discovered she's having twins. She told Page Six: “Twins don’t run on either side of our families so we were completely shocked. This wasn’t IVF or anything like that. It was just a shock, and I’m like, ‘Doctor, that’s impossible!'” She and her boyfriend Hamzi Hijazi have been expecting for quite some time now, but she has a 10-year-old son named Dezi from her former fiancé Eric Calvo. She opened up about Dezi's excitement as the big brother-to-be: “He’s been begging Hamzi and I to give him a sibling since he was in kindergarten. He’s very patient and sweet and gentle and is going to be the best babysitter ever. He’s constantly kissing my belly."
