From the crazy up and down friendship we once had, to someone I now call my brother ? @mikethesituation, big daddy Sitch, BDS, the inspiration... you are an incredible human. I’m so honored to call you my friend. Your star shines brighter everyday. Can’t wait to see you and @lauren_pesce tie the knot."

"So excited to celebrate this amazing couple tonight," co-star Deena Cortise wrote on her Insta Story. She later posed a shot of her makeup when she was getting ready for the ceremony.

The groom also shared sweet words for his fiancé. "Today I marry my best friend," he captioned a photo of him and Lauren on Instagram. "My College Sweetheart, My everything. Together as a team we can accomplish anything. I am so grateful that you are by my side. I promise to be my best self everyday & make you proud to call yourself Mrs. Sorrentino.
