Reps for Demi Lovato are furious at her dad’s claim that she’s called him from rehab, where she’s seeking help for “emotional and physical issues.” Patrick Lovato reportedly said Demi called him and “told me she loved me, she really loves her daddy.” But the Disney star’s rep said, “Not true. She hasn’t spoken to her dad in a long time. He is making false claims.” Sources say the two have not been close for years. We reported last week that Disney lawyers warned Patrick to keep quiet after he gave an interview about her issues.
