The couple shocked fans over Christmas after they confirmed they had tied the knot in an intimate ceremony, with just their family present, and it has now been revealed that they got their marriage license in Williamson County, Tennessee on December 18.

Paperwork obtained by TMZ shows the couple went to the office to sign on the dotted line and they now have 30 days to complete the document and return it to the courthouse with officiant's signature on.

Miley confirmed her marriage to Liam by sharing a string of black and white photos from their nuptials this week, a decade after they first met while shooting 'The Last Song'.

In one set of pictures of the pair embracing, Miley - who wore a floor-length white Vivienne Westwood gown - captioned the Instagram post: "12.23.18"

And alongside another, she wrote: "10 years later .....(sic)"

A third post featured the couple sharing a kiss and the 26-year-old star wrote: "This is probably our one - millionth kiss. (sic)"

The 'Hunger Games' actor shared the same kissing photo, which he captioned: "My love [heart emoji]."

The couple had planned to wed over the festive season at their Malibu home, but after it was destroyed by the California wildfires last month, they shifted their celebrations to their house in the 'Nothing Breaks Like a Heart' singer's home state of Tennessee instead and had a "perfect" day.

A source said: "They always wanted a small, private celebration with family and close friends and that's what they got. Miley seems ecstatic. She loves her Tennessee home and was very happy about having the ceremony there."
