The actor has had to face these rumors on numerous occasions, but has always been able to dispel them.
Ashton Kutcher has been in the midst of infidelity rumors more than once, first starting when he and actress Demi Moore ended their marriage. But the actor has always been above it.
Most recently, Star Magazine decided to slander the actor when photos were snapped of him getting out of his car with a mystery woman who seemed to bear resemblance to his wife, Mila Kunis, reported Shared.
Unfortunately for the sleazy tabloid, Kutcher had an excellent response to them trying to start up cheating rumors yet again.
“You should have heard how upset Mila was that I spent the day with our cousin," he wrote on Twitter. "Sorry aunt Jodie these magazines lack integrity."
Kutcher also addressed the other cheating rumors from his split with Moore at an awards ceremony.
In his home state of Iowa, the actor was given an award for his good character, and he used his acceptance speech to say a few words on his supposed infidelity.
He believes he is likely the first person to be presented with this particular award when just half a decade earlier people believed that his marriage had ended because he was having an affair.
“Character comes when those magazines tear you apart for something you may or may not have done and you gotta go out and perform tomorrow — with everyone looking at you like you might be an adulterer," he said.
Kutcher has proven on more than one occasion that he is actually an amazing human being, not just on-camera.
The actor has a twin brother, Michael, who was born with cerebral palsy. When the boys were just 13, Michael suffered a cardiac arrest, and needed an urgent heart transplant.
In his early teens, Kutcher stood on the balcony of the building and seriously contemplated jumping off so that his heart could be used to save his brother. Fortunately, he was saved from doing that when his father found him.
Michael received a heart just in time, and Kutcher's sacrifice was unnecessary.
Kutcher has also shown his humanitarian side in other, less personal ways. He runs a nonprofit organization called Thorn. The company develops software to help law enforcement identify sex trafficking victims.
"You can roll up your sleeves and go try to be like a hero and go save one person, or you can build a tool that allows one person to save a lot of people," the actor said about his charity work.
And despite the constant infidelity rumors that tabloids dream up, Kutcher also always makes time for his wife and children. Kutcher and Kunis first met on the set of That 70's Show, where they played one another's love interests.
At the time, their relationship outside of the show was purely platonic, although Kunis admitted she had a bit of a crush on him even back then. They also shared an on-screen kiss, which was actually Kunis' real-life first kiss.
Years later, when Kutcher split from Moore, the pair finally got together as a couple, and neither has looked back since!
They shared a daughter and a son together, 3-year-old Wyatt Isabelle, and 1-year-old Dimitri.
