Renee Zellweger has claimed that she misses her carefree waitressing days.

The Academy Award-winning actress has admitted that she gets nervous at film premieres and was happier before finding fame.

"I did some work on a farm and in a bar - they were the happiest times in my life - I had no worries apart from serving tables," she told The Mirror.

"Why am I not a 'look at me' girl? When I face walking on the red carpet before a premiere, I am terrified by the wall of photographers screaming my name. It is so violent. When I first went to Hollywood, I remember working for two years in a bar. I was happy when all I had to worry about was the labels on the bottles."
