Rapper and CSI: Cyber actor Shad "Bow Wow" Moss, 27, popped the question to Love and Hip Hop: New York's Erica Mena, 28, last September.

"I've known Erica for a long, long time," Moss told PEOPLE.

The pair worked together on various projects over the years before reuniting on his BET show, 106 and Park, last February, where they shared an on-camera kiss that set the relationship in motion.
