Olympian Chay Lapin pops the question in front of Andy Cohen.

Last night's Watch What Happens Live featured hilarious interviews with Padma Lakshmi and Tamar Braxton…and a surprise marriage proposal!

Olympic water polo goalkeeper Chay Lapin was stationed behind the bar, but before the live show ended, he popped out to introduce Andy Cohen to his love of five years, model/actress Kim Nelson—and to her ask her a very important question.

"I wanted to catch you off guard," Lapin says as a stunned Nelson responds, "What the heck?" He continues, "And tell you I love you and I want to spend the rest of my life with you."

As the audience went wild, Nelson responds, "Oh my God, Chay are you kidding me?" before adding an enthusiastic, "Yeahhh!"
