Erin Moran, Mother in Law in Drunken Brawl After Happy Days Star Snuck into Trailer

"Happy Days" star Erin Moran got into a drunken brawl with her mother-in-law after she tried to sneak into the 72-year-old woman's trailer home in the middle of the night.

Moran was living with her husband Steve Fleischmann and his elderly mom in a trailer park in Indiana until she was kicked out for non-stop partying, according to National Enquirer. The child star who played Joanie Cunningham on the popular sitcom has been homeless, going from one motel to another and burning through all her money.

The couple had asked the mother-in-law if Moran could move back in but their request was denied.

That's when Moran resorted to sneaking into the trailer after her mother-in-law went to bed. However, she was caught while trying to slip in. Steve's mom threatened to call the cops if Moran didn't leave.

Moran eventually got into the car to leave but not before she and her mother-in-law got into a fight.

"She finally did leave, but Steve's mom was right on her heels, chasing her out of the trailer, shouting at Erin as she made her way across the yard to their car," a close family friend told the Enquirer.

"Steve's mom was standing in the street in a nightgown and hair curlers, and the two women were screaming profani­ties at each other."

Moran's family friend said the family is afraid she will end up dead if she doesn't change her ways.

"It's evident that Erin's living situation has become more dire than ever before," the source added. "She's desperate and quickly running out of options."

Recently, witnesses told Radar Online that Moran was spending money like a "drunken sailor" and enjoying a random night of drunkenness near the Indiana motel where she was staying.

"She said she was heading over to the bar for a tequila shot, but actually stayed with us instead and hung out for the next three or four hours outside in the grass," the source said.
