Keyshia Cole has fired her manager because of slow first week album sales, she has revealed. 

The singer's latest album, 'Calling All Hearts', was met with a disappointing reception and Cole decided to release her long time manager, Manny Halley, of all duties. Cole tweeted (January 17):

"Would like for u guys to know tht Manny Halley is no longer my management."

She then followed up the message with a final statement:

"Someone said if the people around u won't change, change the people around you."

Billboard.com explained that the record's first four weeks of release only brought in 194,000 sales whereas her 2008 album, 'A Different Me', shifted 539,000 copies in the same amount of time.
