BUDDY HOLLY’s widow MARIA ELENA has launched a legal battle to block a tell-all memoir by the woman made famous in the rocker’s classic hit PEGGY SUE.

Peggy Sue Gerron - who was married to Holly’s drummer - was said to have inspired the 1957 track and insists she enjoyed a close relationship with the singer.

And now Gerron is set to release Whatever Happened to Peggy Sue? - a book about the time she spent with Holly.

But Maria Elena Holly - who married the star in 1958 - was infuriated by the book’s claims that her late husband longed to run away with Gerron and has launched a lawsuit in a bid to stop it being published.

A cease and desist letter written by Holly’s lawyers states: "Confusion and tarnishment of Buddy Holly’s name and Mrs Holly’s reputation are likely to result from this unauthorized book." Gerron says, "It’s very interesting that this woman makes up all these stories. He never, never considered Peggy Sue a friend." Buddy Holly was killed in a plane crash in 1959 at the age of 22.
