Actress Isla Fisher was once left red-faced after she was introduced by a Hollywood party hostess as her fiancé Sacha Baron Cohen's "daughter."

The Wedding Crashers star, 33, has been dating her comedian beau, 37, for several years and the couple share 16-month-old tot Olive together. However, Fisher recalls one cringe-worthy incident when her youthful looks belied her real age - and led the socialite hostess to believe she was just a child.

She says, "When we first came to Hollywood we went to one of these Oscar parties held in this prestigious lady's home and we showed up and she opened the door and said to me, 'Come with me, hello and welcome.' I was very excited, I thought I was gonna get to meet a big celebrity. She let me into this room and there were these six 15 year old girls and she goes, 'Everybody, play nicely with Sacha Baron Cohen's daughter!' It was particularly awkward!"
