Jennifer Lopez

R&B singer Jennifer Lopez has reportedly parted ways over the weekend with her manager of over a year, Jeff Kwatinetz, head of management company, The Firm. Reports say she was not satisfied with his ability to come through on expectations.

The actress-singer-fashion icon's last year, has been disappointing professionally. Her 2005 album "Rebirth" was a flop and though her role in "An Unfinished Life" with Robert Redford and Morgan Freeman was critically praised, the film itself failed to generate the expected awards.

The split comes before J.Lo hits the road for "Bordertown," scheduled for release in October, in which she plays a journalist investigating the murder of young female factory workers and stars with Antonio Banderas and "El Cantante," a biographical account of one of the pioneers of salsa, Hector Lavoe, in which she stars alongside her husband Marc Anthony. Her album of Spanish-language ballads "Como Ama Una Mujer" ("The Way A Woman Loves") is also scheduled for release later this year.

"Jennifer is a dear friend of The Firm and will remain so regardless of the business relationship. This was a decision based on differing styles and expectations and we wish her the absolute best," TMZ quoted The Firm, as writing.
