“Should have slapped mother and sister in the face”

Britney Spears (40) publicly fires against her family. In an Instagram post, the pop star wrote that she wishes she “slapped her sister Jamie Lynn Spears, 30, in the face” and her mother when she had the chance.

She claims in an Instagram post, which she has since deleted: “My mom took painkillers and could hardly talk in the house because she and my father broke up. She was more confused than anything.”
