OK reports that the actress, who is rumoured to be expecting her first child with Muse frontman Matt Bellamy, is trying to distance herself from speculation that her biological father Bill is shopping a tell-all book about her and her mother Goldie Hawn.
A source said: "[Kate and Matt are] in that super-excited new parent phase.
"She tries to wave off drama and negative energy. She thinks it’s bad for the baby."
Kate is reportedly three months pregnant with her second child, who will be a sibling to her 7-year-old son Ryder, from her marriage to Chris Robinson.
