"The Bachelor" may be over, but Ben Flajnik and Courtney Robertson are still making everyone watch them make out!

The two locked lips on the red carpet last night at SVEDKA's 2nd Annual Night of a Billion Reality Stars at SupperClub in Los Angeles, where Courtney proudly showed off her impressive Neil Lane engagement ring while posing for cameras.

The event was packed with your favorite (or most hated) reality TV stars, including "Real Housewives" franchise members Kyle Richards, Teresa Giudice, Gretchen Rossi and Brandi Glanville, "Mob Wives" star Renee Graziano, Jon Gosselin, "Bachelorettes" Ashley Hebert and Ali Fedotowsky and "Dancing with the Stars" stud Maksim Chmerkovskiy.

While at the event, Ben and Courtney reportedly enjoyed some "alone time" at the "Smush Room" cocktail area.

Teresa also locked lips with someone at the event -- a cardboard cutout of her husband, Joe!
