London, May 26 (IANS) British comedian Russell Brand says it was love at first sight for him when he met fiancee, singer Katy Perry.

‘I immediately knew that it was either concussion or love. After that we went on a date and I was anxious and nervous on the date,’ femalefirst.co.uk quoted him as saying.

‘Normally, like on the first date I’m alright… But this one I felt all anxious like my mind was awash with hallucinations peculiar! I had to hold on to surfaces.

‘I thought it was either something wrong with my starter or love. So now we can narrow it down to concussion or food poisoning or love,’ he added.

The ‘Forgetting Sarah Marshal’ star, who has been dating Perry since September last year, proposed to her just three months after they met.
