Cradle- robber DEMI MOORE is at it again – this time in a trial marriage with her daughter Rumer’s ex-boyfriend while waiting to finalize her divorce with estranged hubby Ashton Kutcher!

Sources tell The ENQUIRER that the smitten film beauty, 50, has allowed Hollywood play­boy Harry Morton, 32, to move into her Beverly Hills home.

“Demi is crazy about Harry,” revealed an insider.

“She says that he makes her feel more alive than she has in years. She’s convinced this relationship is built to last – despite Harry’s reputation for loving and leaving women.”

Restaurant tycoon Morton – who’s worth an estimated $120 million – has dated a slew of Hollywood beauties, including Lindsay Lohan and Jennifer Aniston.

He also had a brief fling with Rum­er, 24, in 2007, and when the starlet found out that Demi was now dating him, she “was absolutely disgusted,” said the insider, adding that it led to a bitter falling out between the two.

Since Demi split from Ashton, she has cycled through hookups with New Zea­land actor Martin Henderson , sing­er Lenny Kravitz and art dealer Vito Schnabel.

 She’s still wrangling with the “Two and a Half Men” star over their divorce, and started dating Morton late last year.

“Demi and Harry kept things casual for the first few months, but now she can’t get enough of him and he’s moved in with her,” confirmed another source.
