We never go out drinking or anything like that.'"I just laughed and said 'Well, you are quite popular, Angelina. I don't know how you do it, smiling for the cameras all the time.'"She just said it was part of the job."The 27-year-old photographer was following the 32-year-old actress' car on his bicycle when he ran over a nail and got a flat tyre.

He said: "When I realised I'd got a puncture I thought I was going to lose her and not get any pictures.

"The next thing I know, Angelina's car is pulling over, Angelina winds her window down and says 'Lance, why don't you jump in the car?'

"She told me the family were so impressed that I was able to keep up with the car, they had nicknamed me after Lance Armstrong.

"She said, 'We love having you riding alongside us. You're always happy, always smiling. The kids enjoy watching you whizzing along on your bike.'

"I got in and said, 'This is so strange'.

"She just laughed and said, 'Well, it's a strange world we live in.'"

"She was one of the nicest people I have ever met. And it was one of the most surreal experiences of my life."
