Starting 2017 as Mr and Mrs? Miley Cyrus and Liam Hemsworth may have been celebrating more than the New Year as they marked 2017 with a passionate kiss, amid reports the couple tied the knot in secret at the San Diego party

'It was all extremely last-minute,' a source allegedly told the magazine, who added that family were told just hours before the wedding took place.

'Liam's entire family flew over for the holidays and the Cyrus family were in town too. It just seemed like a no-brainer to do it while everyone was together,' they noted.

On the night, Miley posted a photo with the hashtag 'in laws', featuring Liam and Chris's mum, Leonie Hemsworth, with her mum, Tish Cyrus, and with Elsa Pataky's mum Cristina Pataky Medianu.

The publication claims the couple wrote their own vows for the ceremony, confessing that they were each other's soulmates.

It's also reported the couple are hoping to start a family soon. 

Daily Mail Australia has contacted the couple's representatives for comment.
