18 years and counting!

"Real Housewives of Beverly Hills" star Kyle Richards posted an adorable snapshot via Instagram on Sunday, posing on her wedding day with her hubby Mauricio -- and she hasn't changed a bit!

On her big day, the brunette beauty wore an off-the-shoulder lace wedding gown and delicate veil, sweeping her signature long locks away from her face in an elegant up 'do. Her man sported a classic black and white tux.

Maybe her marriage has kept her looking young! 

Kyle's relationship with Mauricio has been a hot topic of the season on the show -- and she's ready to move past all the "lies."

In an exclusive interview with toofab's Anna Kachikyan, the 45-year-old opened up about how her family has been dealing with some of the negative press -- and how she prepared her four children for all the unwanted media attention.
