Sunday night NeNe Leakes was spotted at TAO with her husband Gregg celebrating their anniversary.  Dressed to the nines, the couple toasted with cocktails while enjoying appetizers and sushi from the Asian bistro.  Guests nearby noticed the reality star and stopped by her table to say hello. Leakes, of Real Housewives fame, is in Vegas to guest star in Cirque du Soleil’s Zumanity.
