It was Mother’s Day and she had invited 300 people in her family there. It was her first Mother’s Day as a mom and she could not do it. At that point she said “I am going to have to pass”. I said “I think you are making the right decision. You have a new baby, you have survived breast cancer and Lance Armstrong. I don’t think this is the right thing for you”. That is what happened with Sheryl Crow. She is still our friend and I still adore her. She is one fm my dearest friends”.“Extra’s” interview with Sheryl Crow and more from Unforgettable Evening airs tonight.
