Legendary R&B singer Natalie Cole passed away on December 31 at the age of 65 due to complications from ongoing health issues. However, her stunning voice, unforgettable music, and lovely personality will live on. Not only did Natalie have a memorable appearance on Season 4 of The Real Housewives of New York City when she performed with Luann de Lesseps at the Countess' anniversary party for then-boyfriend Jacques Azoulay, but she has also made an extraordinary impact on several Bravolebs. Everyone from Luann to Andy Cohen to The Real Housewives of Atlanta's Cynthia Bailey paid their respects to the late chanteuse. Check out all of the touching tributes on social media, below.
