They said it wouldn’t last….And they guessed correctly!

The celebrity hound dogs over at the bastion of truth that is Star Magazine have dug up an explosive report that could blow the lid off the May/December union that changed the way the world looks at old broads who shag floppy-haired twentysomethings.

Word on the Curb has it that Ashton Kutcher has been making sexy times with a hot little blonde unbeknownst to his actress wife Demi, now 47. While the pair have always seemed to take their 15 year age difference in stride, tattling tipsters say Ashton’s ready to trade Moore in for a young model. In fact, the Twitter-lovin’ funnyguy has reportedly been sucking face with his new galpal all over Hollywood, while Demi is hard at work shooting scenes alongside teen star Miley Cyrus on the Detroit set of their new coming-of-age flick, L.O.L.

“Ashton had this gorgeous girl pinned against the wall, and he was totally making out with her,” squeals Star’s spywitness, who was on his way to the restroom at Los Angeles Italian restaurant Madeo, when he witnessed Ashton’s indiscretion. “I was shocked to see him sucking face with a girl who obviously wasn’t Demi.”
