I am so sad to hear about Natalie Cole’s passing. I feel she has always been apart of my life in many ways. Before the craziness & now. Her father, Nat King Cole, is my favorite artist of all time. ‘Smile’ is a song I sing to myself whenever things get overwhelming. I sang ‘This Will Be’ on the American Idol tour w/ @mdoolittle, my favorite part of that show. A few years later, I had the honor of actually singing it with her on stage. I don’t remember what I sounded like, I was too much in awe of her. But, I sure remember her standing next to me, voice so pure & clear as a bell. I will never ever forget that moment. She was always so kind & exuded so much grace. Rest in everlasting love. I’m sure the heavens are absolutely loving you and your dad rejoicing together. ‘Unforgettable in every way….’ That you are, Natalie, that you are.??
