Beyoncé has reportedly refused to hand over her private communications with her mother, Tina Knowles and husband Jay Z, to a wedding planner.
The Formation hitmaker, 37, is locked in a trademark battle with Veronica Morales over the use of the name Blue Ivy, the name of Beyoncé and Jay Z's eldest daughter.
The businesswoman has requested a list of documents and communications from the singer to show any evidence she planned to use the trademark and any samples of her intent to use the name.
