Jennifer Aniston says boyfriend John Mayer is "a rare one".

The former "Friends" actress - who is divorced from Brad Pitt -is very happy in her new relationship, and loves watching "Gravity" singer John think and perform.

She said: "John is a rare one. He is extraordinary and it's wonderful to watch him - the way his brain works and the way he thinks his thoughts. It's beautiful.

"It's an amazing thing to watch musicians think. I don't know many musicians but when his guitar is on him it's just like a channel. It's like something I have never, ever seen before."

Jennifer also revealed she doesn't like talking about her relationship with Brad, and thinks people should move on.

She added to Britain's Daily Mirror newspaper: "Everybody goes through tough times, you have just got to figure out how to get through them. It's my history and my memory. I used to really take things personally.

"It took me some time to figure this out but if you can be truthful and honest with who you are, then you have a much easier time walking through life."

The 39-year-old actress says she is not worried about turning 40 next year, and is actually looking forward to the landmark birthday.

She laughed: "I panicked when I was leaving my 20s, and the 30s were quite a challenge, frankly. They were so full, from 'Friends' to everything - that was a decade! Now I'm ready for the next one."
