BRUCE WILLIS is so fed up with ex-wife DEMI MOORE that he’s selling his Beverly Hills man­sion to get away from her, says a source.

The 58-year-old “Die Hard” star recently listed his sprawling 11-bedroom estate on nearly an acre for a whopping $22 million.

“He’s finally had enough of Demi’s crazy antics,” re­vealed an insider. “And since they live just over three miles apart, he wants to put more distance between them.”

Bruce reached the break­ing point when Demi failed to show up for their 21-year-old daughter Scout’s graduation from Brown University over the Memorial Day weekend.

The action hero attended the ceremony in Rhode Island with his second wife Emma Heming and Scout’s sisters Rumer, 24, and Tallulah, 19, who’ve also been at odds with their mom, according to sources.

“Demi’s had a trou­bled relationship with her girls since she left rehab last year,” said the insider. “But it was still a bitter disappoint­ment when she was a no-show.”

Meanwhile, Rumer has had the toughest time with her mother.

As The ENQUIRER reported in May, cradle-robber Demi angered her eldest daughter by beginning a trial mar­riage with Rumer’s ex-boyfriend Harry Morton while waiting to finalize her divorce from Ashton Kutcher.

The 50-year-old film star had allowed Holly­wood playboy Morton, 32, to move into her Beverly Hills home – triggering the bitter falling out.

“Rumer was absolutely dis­gusted,” said the insider.

Demi has since moved on from Morton to a new boy toy, 30-year-old Australian pearl diver and yoga teacher Will Hanigan. She’s also said to be seeking spiritual guidance from Mexico-based astrologer Paddi Moore.

“Paddi’s helping her clear the negative en­ergy out of her life,” said a source. “Demi’s trying to cleanse her karma from all the nastiness of the past.” And all that has ap­parently pushed Bruce to buy a place in Malibu or even farther into the country after his Beverly Hills estate sells. He also has two apartments in New York, a vacation home in the Caribbean and several properties in Idaho.

“He’s had it with all the family drama,” said the insider. “He’s got a new life with Emma and their baby Mabel and wants no part of his ex’s baggage
