Say it ain’t so! According to reports, Ashton Kutcher and Mila Kunis, Hollywood’s hottest couple and Tinseltown’s newest parents, have become the latest celebrity victims to endure a cheating rumor. According to Star magazine, the “Two and a Half Men” actor, 36, allegedly cheated on his fiancée, 31, in 2012, only a few months after the duo had begun their relationship, while he was filming the biographical drama “Jobs.”

So, who is the woman that reportedly caught Kutcher’s eye? Well, according to reports, her name is Linn Massinger, a Swedish makeup artist whom Kutcher spotted at The Writer’s Room, a bar in Los Angeles. After introducing himself to the blond beauty, the actor allegedly flirted with Massinger and her friend for a few minutes before inviting the two over to his house to continue drinking. 

“Everyone sat around drinking at the bar in Ashton’s living room, and then he made his move,” a source revealed to the gossip mag, adding that’s when things started to heat up. “After a while, the other people began to leave, and Ashton took Linn into his cinema. They started making out.”

The insider continued that if the allegations are true, Kunis will be completely “heartbroken” considering she just gave birth to their daughter, Wyatt Isabelle, on Oct. 1. “They’re just now building a life together, and trust obviously has to play a large part in that,” the source concluded.

This isn’t the first time Kutcher has been haunted by accusations of infidelity. Before finalizing a divorce from his ex-wife, actress Demi Moore, in 2013 (for irreconcilable differences), the actor was accused of hooking up with Brittney Jones and Sara Leal while he was still married to Moore.
