The singer, who is just about to release her highly anticipated second album 21, bumped into Puffy whilst promoting her debut 19 in the US.

She told The Sun:

"I was shooting a video on one of the big American plots - six hours I was there and I wasn't doing anything. So I convinced someone to let me drive a golf buggy. I ran the battery out by the end of the day. P Diddy must have been doing a fragrance advert or something.

"I was in the buggy with a mate and I saw him. I meant to put the brake on and go, 'Oh, you're P Diddy!' But I hit the accelerator. He had to dive out the way.

"As we went past I was like, 'You're P Diddy.' He just said, 'Yeah, I know.' I almost, almost killed him."
