Happy Days star Erin Moran has become a recluse after a series of bizarre incidents showing her personal life spiraling out of control, and Breaking Celebrity News has learned exclusively that she’s writing a book about her troubled life.

The actress who shot to stardom as Joanie Cunningham was kicked out of the trailer park where she was staying and is now holed up in an Indiana hotel room writing a book about the difficulty of finding fame at a young age.

In recent months, Erin, 52, has been hotel-hopping around town after becoming homeless and even got into a drunken brawl with her mother-in-law!

"Erin thinks the best thing for her at the moment is to just stay in," a source told Breaking Celebrity News.

"She’s working on an autobiography, which she hopes will help her settle some debts she has.

"Every time she ventures out, whether it’s to a bar to grab a drink or even to the supermarket for some groceries, Erin seems to land in hot water.

"Her husband Steve Fleischmann has been helping her stay out of trouble – but they just don’t leave their hotel room anymore," the source revealed.

Erin’s erratic behavior has made national headlines and just weeks ago she was scheduled to tape an episode of Dr. Phil McGraw’s talk show but didn’t show up, Breaking Celebrity News learned exclusively.

Last month, the National Enquirer revealed that Erin and Steve were booted out of the trailer they were living in with his elderly mother for non-stop partying.
