Russell Brand's ex has urged the funnyman to seek out a psychiatric evaluation before he weds fiancee Katy Perry to make sure he's ready for marriage.
 
Georgina Baillie fears the one-time British Casanova will always be a ladies man - and she worried for his wife-to-be.
 
Baillie, who dated the actor on and off for a year, tells Life & Style magazine, "He (Brand) has a habit of dating a girl for a while, declaring, 'She's the one,' then losing interest quickly...Poor Katy's going to have her heart broken. It would be a good idea for him to get a psychiatrist's opinion (before he weds)...He should really get some help."
