Ashton Kutcher and Mila Kunis share one of the cutest love stories in Hollywood. The couple, who met in 1998, starred in the hit comedy series "That 70s Show" and since then have been best friends, partners and now proud parents of their one year old daughter Wyatt Isabelle Kutcher.

However, all doesn't seem well in their married life. The latest news surrounding Ashton and Mila's marriage suggests that the two are on their way out.

Hollywood Life (via OK! Magazine) reported that Mila is anxious that her husband might cheat on her. The "Friends with Benefits" star can't seem to get over Ashton's past when he cheated on his ex-wife Demi Moore.

"Mila knew that he'd cheated on Demi, and in fact, he was confiding in Mila while all that was going on," a source close to Mila said. 

The source added that the 32-year-old actress even checks her husband's text messages and emails because of a lack of trust between them. Although their marriage seems like a union of best friends, Mila is reportedly worried that things might change since she is his wife now.

According to a report on Hollywood Life, the couple fight incessantly and an insider added that they had a huge argument recently. The insider further claimed that Ashton has given an ultimatum that he wants to have another baby to save their marriage.

Nevertheless, Ashton Kutcher and Mila Kunis were spotted during the Oktober fest celebrations in California. The two wore Bavarian garb and seemed very happy as they dug into their sausages, reported OK! Magazine.

Ashton Kutcher and Mila Kunis tied the knot three months ago, on 4 July 2015, in a private ceremony. The couple honeymooned in Yosemite Park, California and took their baby with them, according to Glamour Magazine
