TROUBLED Demi Moore went to a bikini boot camp in Mexico after her three daughters ordered her to clean up her act – but sources say the sexy cougar spent most of her time chasing young hunks and making life difficult for other guests with her diva antics!

“Demi’s behavior was outrageous,” a guest at the Amansala Eco-Chic Resort in Tulum told The ENQUIRER.

“She skipped out on most of the spa activities and seemed to flirt with every young male in sight, including a 17-year-old. Other guests were furious at Demi for ruining what was supposed to be a rejuvenating beach getaway.”

Demi, 50, showed up at the pricey resort with friends just two days after her third hubby, “Two and a Half Men” star Ashton Kutcher, filed for divorce on Dec. 21.

Sources say her daughters, Rumer, 24, Scout, 21, and Tallulah, 18, had given her an ultimatum to get herself together. “The girls told her that if she didn’t straighten herself out, they’d have nothing more to do with her,” one family friend told The ENQUIRER.

“Besides her embarrassing cougar behavior, they’re even more concerned that she’ll head back down the road of drug abuse. But their idea may have backfired because the whole time Demi was in Mexico, people say she was acting loopy, like she was off in her own world.”

The “GHOST” star checked into the resort under the name “Topper” (from the movie and TV show of the same name – he saw Ghosts!) and insisted that everyone call her THAT.

“Demi was extremely rude,” another guest told The ENQUIRER. “She hung out with her friends and refused to talk to anyone else. She kept saying, ‘Don’t look at me!’”

The actress indulged herself with daily massages and acted like a fool during a meditation ses­sion, added the second guest. During the group meditating ses­sions, guests covered themselves with clay.

“While most of the other women were standing, Demi laid down and started do­ing some weird dance,” said the source. “She was rubbing her wrinkled belly and chest, and lift­ing up her legs.”

And she seemed to be constantly on the prowl.

“Demi threw herself at every young, attractive man in the place, including a masseur and a yoga instructor,” said the second guest. “She even hit on a 17-year-old. He told me, ‘She was totally throwing herself at me. It was embarrassing. She’s old enough to be my grand­mother!’

“A guest who had the room below Demi’s COMPLAINED that on at least two nights she could hear moaning, groaning and squeaking bed noises coming from Demi’s suite.”

And although the actress showed up for lunch and dinner, she chugged the energy drink Red Bull instead of eating, said the second guest.

“It’s obvious Demi’s got eating issues,” noted the source. “She’s so skinny that the bones in her spine stick out.

“She’s clearly feeling her age and grabbing at her last chance to feel young and desirable. But she just comes off as pathetic.”
