This Sunday is father?s day, and celebrities know how to celebrate it big. For fathers day pop singer Rihanna, aka Robyn Rihanna Fenty, bought her father a house. Her father told the press, ?Robyn was so kind. She sent me a few houses to choose from around the island. I chose this, no because it was the most expensive, but it?s got the gardens. I?m hoping when I have the strength and energy to spend more time out there I can build a water feature.
