Britney Spears has said we live in wild word in her first interview since her child custody battle started. Speaking about reports spread on her parenting skills, the pop star said on Ryan Seacrest radio show, "People say what they want and do what they do. It's sad how people... how cruel our world can be." She also claimed that she is doing the best that she can and that's what matters at the end, "But at the end of the day you got to know in your heart that you are doing the best that you can. "You just try to keep doing what you do and as long as you know what's up and you know what's true, that's all that really matters," she said.
