Miley Cyrus thinks boyfriend Liam Hemsworth is "The One".

The 19-year-old star is totally smitten with the 21-year-old Australian actor and has apparently been telling friends she thinks he could be the guy for her permanently.

Miley and Liam are currently busy making plans as to where they will be spending the Christmas period but although they will definitely be together they aren't sure which family they are going to be staying with for the big day.

A source told "It couldn't be better between the both of them. They are figuring out where to spend the holidays together, but it will be together and they are madly in love and inseparable. Miley thinks Liam is 'The One'."

The pair first met on the set of 'The Last Song' in June 2009 and shared an 18 month relationship which ended in November 2010.

They rekindled their romance in the summer and Miley recently described Liam as the perfect boyfriend because he is such a great listener.

The former 'Hannah Montana' star - whose father is country singer Billy Ray Cyrus - recently said: "I think it's someone that is always there to listen and I think that's when people make mistakes because they always want to have the answers and I don't like people trying to fix me, I just like them being able to listen. But everything's great, I'm happy and there's nothing I can complain about. I'm performing and doing what I love and I have awesome people in my life so nothing can really go wrong."
