Ashton Kutcher and Mila Kunis, one of Hollywood's most adorable couples, have reportedly tied the knot over the Fourth of July weekend. While reps haven't commented on this officially, the latest reports suggest that the couple made their relationship official by getting married in a private ceremony.

Could it also be because Kunis is pregnant with second baby?

The "That 70s Show" co-stars met on the sets of this Fox sitcom in 1998, began dating in 2012, got engaged in 2014 and welcomed daughter Wyatt Isabelle in October 2014.

Rumours about the couple being married went wild when Kutcher posted a cryptic message --- "Happy New Year from the Kutchers", on his Facebook in December 2014. A few days later when  late night show host James Corden asked "Are you married? Did you get married? Have you gotten married?" Kunis replied "I don't know. Maybe."

Having kept fans guessing for months about their marital status, a source told People that Kutcher and Kunis finally exchanged vows and said "I do" in a private ceremony over the weekend. It was also reported that the few guests who were invited to the ceremony, were not told even until 24 hours before the wedding.

Meanwhile, other reports suggest that the couple may have tied the knot because baby No. 2 could be on the way. According to Hollywood Life (via Life & Style), a second child may happen soon as the couple has agreed to have back-to-back babies.

"They both agreed they want back-to-back babies and would love to be able to announce a pregnancy by the end of this summer. Their daughter has brought so much joy to their lives that having another child is their main priority. Mila knows it will double the workload, but she doesn't need any convincing," a source said.

But before that, Kunis wants to get a few more films, the website reported. "A second child will happen. It's definitely in their future, but Mila wants to get a few more films under her belt before baby number two arrives. The earliest they are thinking is late next year. It's going to be a little bit before it happens," the source added.

Apparently Kutcher, who has a twin brother Michael, is hoping Kunis gets pregnant with two babies. ""He's secretly hoping Mila will get pregnant with twins," a source said.

Well, now let's just wait to hear it from Ashton Kutcher and Mila Kunis themselves.
