"To the most beautiful person in the world, thank you for your divine love, your eternal support and for being my best friend," the post, accompanied with a black-and-white photo of the pop icon, read. "I love you so much, inshallah we will be together in the Great Forever x."

Earlier this week, a source close to the Jackson family told ET that the 50-year-old singer is doing well despite the breakup.
