Ciara reignited a long-standing feud with Rihanna after calling her 'nuts' during an interview with San Francisco's Wild 94.9 radio station. After insinuating the "Umbrella" singer is crazy, Ciara tried to diffuse the situation by saying, "She has a lot of good things going on with herself. A lot of good things I’ve always said I’ve been happy for her…I don’t get it. I really don’t, but I wish her well. I wish her positivity."
