Ashton Kutcher and his legal team have taken aim at a tabloid after it published a cover story claiming he cheated on his wife, Demi Moore.
On Wednesday, the actor hit his Twitter account to lash out at Star magazine, which claimed in its latest issue that the celebrity couple's marriage "is in danger of falling apart" because the mag claimed the actor was allegedly "caught cheating with a sexy, young, 20-something."

"I think Star magazine calling me a "cheater" qualifies as defamation of character. I hope my lawyer agrees," Ashton Tweeted on Wednesday.
"STAR magazine — you don't get to stand behind 'freedom of the press' when you are writing fiction," he added.
Ashton's wife, Demi, backed him up, reTweeting her husband and adding her two cents.
"No question!," she wrote in response to his defamation of character Tweet.
Demi also called her husband's Tweet, an "Excellent point my love!"
