The 26-year-old actor reunited with his former fiancee - who he split from in 2013 after three years together - over the Christmas period and though she has been sporting a ring on her fourth finger in recent months, the Australian hunk insists that doesn't mean they are planning to wed again.

He said: "I am not engaged, no."

Despite his fame, Liam insists he doesn't deliberately court attention and prefers to "fly under the radar".

He told TV Week: "It is what it is and I am not someone who is looking for any more attention that I have and I try not to draw attention in any way. I don't do things that do draw attention. So most of the time I fly under the radar. There is a lot of attention there but I did have a helicopter flying over my house for a while."

And the 'Independence Day: Resurgence' actor - who was spotted holding hands with Miley at 'The Huntsman: Winter's War' premiere in California earlier this week - has been able to stay out of the spotlight for the last few months after suffering a back injury.

He said: "I just don't leave my home. For the last few months because I had a back injury I really couldn't do much. So I have honestly been at my house most of the time."
