hurtful

The Grammy Award winner, 43, has already denounced her ex's memoir, writing on social media that Federline's revelations have been "extremely hurtful and exhausting".

"People go through that, he has apologized for the stupid remarks, the hurtful remarks that he made, and I'm confident that he's going to run a great campaign and that he's going to win."

She described the contents of the memoir as "extremely hurtful and exhausting", but suggested the work would sell better than her own memoir had done.

“There’s even a term for it—delayed grief—and this itself is very, very hurtful.”

He said the woman had a "strong" and "unusual" personality and concluded that the children had been upset when "unwise and hurtful things were said about the father".
