Keyshia Cole’s former manager Manny Halley has lost another R&B client, according to my well-placed industry source.

Singer Tank, whose last album was 2010’s Now Or Never, fired Halley and Imani Entertainment citing “creative differences” with the way his career was being handled.

Tank, whose real name is Durrell Babbs, is telling friends that Manny (pictured at right with former client Keyshia) was a bit too disorganized for him. But the 35-year-old hasn’t had a top ten hit since forever.

This has not been Halley’s year since losing Keyshia Cole as a client and then seeing his LA Phillipe Chow restaurant franchise finances go into the red.

But Cole’s journey through managers hasn’t been an easy one either.

The “Calling All Hearts” singer hired industry veteran Ashley Fox of Ashley Fox Management to guide her through the separation from Imani Entertainment last year. Next, Keyshia dumped Ashley Fox for Über manager Chris Lighty. But that union only lasted for a month.

Then last week, Keyshia announced on her Twitter page that she was being managed by Kevin Liles, the former president of Def Jam, who also manages singer Trey Songz.

Manny is a friend to the blog. So we wish him well, and we know he will keep doing big things.
