Superstar JENNIFER LOPEZ has reportedly hired BRITTANY MURPHY’s former fiance JEFF KWATINETZ as her manager.

Kwatinetz’s agency THE FIRM manages a host of A-list stars, including ADRIEN BRODY, CAMERON DIAZ, KATE HUDSON, LEONARDO DiCAPRIO, MANDY MOORE, MARTIN SCORSESE, NATALIE PORTMAN, ORLANDO BLOOM, ROBERT DE NIRO, SARAH MICHELLE GELLAR and SNOOP DOGG.

According to gossip site PAGESIX.COM, Lopez has plumped for Kwatinetz to take over duties from temporary manager SIMON FIELDS, who will revert back to his original position as production partner.

Kwatinetz is expected to focus on boosting sales of J.Lo’s latest album REBIRTH following poor reviews and figures.

Murphy and Kwatinetz ended their four-month engagement last May (04).
