Sinead O'connor has parted ways with her manager after revealing she fell for him and carried on an affair behind his girlfriend's back.

In a new post to her blog, the Irish singer reveals she's looking for a new svengali to take care of her business affairs after her professional relationship with her last manager turned personal.

The Nothing Compares 2 U singer writes, "Have had to leave my manager. Not that we didn't get on well, we got on too well, both fell equally in love. Had a month long affair, but he has a girlfriend, so naturally I gotta vanish. Extraordinarily sad and depressing, but there it is. Another manager bites the dust.

"So now I need to find a new manager and I haven't a f**king clue where to start."

And she admits her latest love connection wasn't a happy one: "Been secretly f**king miserable as a motherf**ker since the second it started. Wasn't at all proud of myself. Or him.

"Never, ever messing with someone else's fella again. Its (sic) the most disgusting thing a woman could possibly do to another woman. And it smacks of zero self-esteem. So, back to the therapist for Sinead."

O'Connor was set to remarry her fourth husband Barry Herridge, a therapist, earlier this year (14), but the couple opted to stay friends instead.

Concluding her latest blog entry, the singer has asked fans to recommend anyone they think would make a suitable manager adding, "If anyone knows anyone who might be interested in managing me could they please e mail me at I do not have a career in America, my career is European based, so it needs to be someone who is familiar with the European market. While waiting for the right permanent manager I could do with a 'temp' so if you know anyone please let me know."
