"Well... I got it," he posted alongside the photo of him on one knee asking his love to marry him. He also shared a heart and ring emoji alongside the moment, which took place the same weekend Pride month kicked off.
The photo prompted some key reactions from those in Greg's inner circle, including The Real Housewives of New Jersey alum Caroline Manzo who commented, "This makes me very happy/love you both!! Congratulations."
Albie Manzo also shouted out his BFF's new chapter, writing, "Seeing this absolutely could not make me any happier. Congrats to one of my best friends on the planet. This wedding is gonna be a trip [and] a halffffff. Love you guys!"
Oh yeah, so did The Real Housewives of Beverly Hills' Lisa Rinna, who commented from the West Coast, "YAY!!!!!!! Congrats!!!!!!"
Alex also shared some post-engagement moments over the weekend, proudly showing off the bling his future hubby popped the question with on Instagram.
