New parents Ashton Kutcher and Mila Kunis are being hounded by cheating rumors. 

Reports are saying that Ashton allegedly flirted with Linn Massinger, a makeup artist, several months after he and Kunis went steady. According to IBTimes and the Heat World, a Star Magazine report mentioned that the two met at an L.A. bar called The Writer's Room. The publication's source further stated that they continued their drinking session in the actor's house along with another friend.

Nothing happened between the "Jobs" actor and the makeup artist, sources claimed, but they only reportedly made out in the actor's cinema room.

However, just like the rest of the cheating rumors that the actor previously faced, the latest allegations might just be fake.

US Magazine wrote about the speculated infidelity of Kutcher when he was still married to Hollywood actress Demi Moore. Kutcher was allegedly involved with Sarah Leal who was only 22 years old then. About seven weeks after the cheating story broke out, Moore put an end to their relationship.

Kutcher's divorce with Moore was finalized due to "irreconcilable differences."

Brittney Jones was another alleged mistress of the young actor. She claimed that she had couch sex with him in September 2010 and that it happened right inside the home that Kutcher shared with Moore and the actress' daughters with ex-husband, Bruce Willis.

All these were denied by the actor's reps and Kutcher himself vented out on Twitter saying, "I think Star Magazine calling me a 'cheater' qualifies as defamation of character. I hope my lawyer agrees."

This could be solid proof that these new cheating rumors Kutcher is involved in might just end up in another court case against the controversial magazine.

Meanwhile, Kutcher and Kunis have started building their life together with their baby daughter, Wyatt Isabelle.

The actor shared with Conan O'Brien the tedious name selection process he went through with Kunis.

After selecting the name, he revealed that they "immediately went home and reserved all the domain names. We've got the Twitter handle - the Instagram - everything you could possibly get - I don't want a porn site with my daughter's name!'

"As soon as this child was born, I immediately wanted to call my parents and just apologize because I never knew how much they loved me," he declared.
