In the latest issue of Us Weekly (on stands Friday), a source reveals that single mom Maynard, 26, was shocked to learn that her fiance, 28, was shopping a tell-all about their split to magazines. "Reporters were calling her asking, 'Will you comment on the story?" the source reveals. "She was blindsided."
An insider says Maynard (mom to Ricki, 7) "is sad and embarrassed about Jef."
