Did Mila And Ashton Secretly Get Married? (VIDEO)

Mila Kunis had everybody guessing during her appearance on James Corden's debut as host of CBS's Late Late Show Monday when she sported a suspicious-looking band on her ring finger.

Kunis never said what the piece of jewelry actually was, but Corden announced to the audience, "They are married!"

But a source tells Us Weekly that Kunis and fiancee Ashton Kutcher did not tie the knot, despite rumors to the contrary, and are concentrating on raising their 5-month-old, Wyatt.

The marriage rumors were kicked off by a Facebook post shared by Kutcher on New Years' Eve which he signed "The Kutchers".

Here's video of Kunis' appearance on The Late Late Show with James Corden, along with fellow guest Tom Hanks.
