Fans know that Mila Kunis, 31, and Ashton Kutcher, 36, who both co-starred on the long-running television show, "That '70s Show," from 1998-2006 have been together since 2012.

Having been engaged since last February, the couple recently welcomed new daughter, Wyatt Isabelle on October 1, 2014. Rumors have been circulating since New Year's that the couple may have secretly gotten marriage, hiding their nuptials from the media.

According to People Magazine, the rumors started up when Ashton Kutcher posted a photo of New Year's wishes to the couple's fans written in sand. It was signed, "Love, The Kutchers." Reps for both Kunis and Kutcher neither had confirmed nor denied the wedding rumors in January. But that didn't keep the rumors stopped that the two had wed in secret.

Since then, Mila Kunis, star in the new film, "Jupiter Ascending," appeared with Ellen DeGeneres on her talk show. Though Kunis was appearing to promote her new fantasy and action film which is in theaters now, DeGeneres dug deep to try to get to the bottom of this rumor. Kunis did not take the bait.

According to People, DeGeneres said, "It's my duty - I'm your friend - but it's my duty as a talk show host to ask you the question if you are married." This gave Kunis full range to answer the question but instead, she offered a mischievous smile and replied, "I don't know. We could just be a plural. My daughter has his last name, legally," she said, "So there's multiple Kutchers."

While on the talk show with Ellen DeGeneres, while she dodged the question, she was more than happy to divulge information about her 4-month-old daughter and how she felt being a new mother.

Whether or not they are really married, Kunis is in charge of feedings while Kutcher is on diaper duty. Even ABC News said on its website that she wouldn't crack whether or not the two had exchanged nuptials.

Looks like the rumors will keep swirling until Kunis and Kutcher are ready to open up on whether or not they have already secretly exchanged vows. From Kunis' coy approach, one might speculate that she has something to hide.
