Rihanna's former pastor has condemned her wild lifestyle.

Bishop Vibert Lowe - who preached to the party-loving singer and her family at their local church in Barbados - says he is ''praying'' for the 24-year-old 'S&M' singer.

The 64-year-old clergyman said: ''A lot of people have been praying for her and hoping that she will drop these bad habits.

''We feel it's wrong for her to behave like this. As a young lady she's not setting a good Example.

''Young people look to her as a mentor, they regard her as an idol and copy her lifestyle. There are people on the island who think she parties way too hard.''

On the subject of Rihanna's collaboration with ex-boyfriend Chris Brown - who assaulted her in 2009 - Bishop Lowe said: ''After all he did, I'd tell her to steer clear of him. He's not the correct influence on her life.''

He added: ''I don't see her much when she comes back - she seems too busy - but she should spend more time in church.''

Hollywood stylist Phil Bloch - who has known Rihanna for several years - admits he is also concerned.

He told The Sun newspaper: ''I went to one of her concerts and was shocked by what I saw. She has no idea how to cope with this level of fame.

''She needs to calm down and behave - I think she's a troubled girl. She's talented and beautiful, but puts herself in Dangerous situations.''
