Singer/songwriter Sara Bareilles has reportedly hired Bruno Mars' music man Brandon Creed after falling out with her longtime manager, Jordan Feldstein.

The Brave hitmaker reportedly split from Feldstein, who represents acts including Maroon 5 and Robin Thicke, within days of the Grammy Awards last month (26Jan14), following rumours he was embroiled in an ugly spat with rock matriarch Sharon Osbourne.

During Clive Davis' annual pre-Grammys party, photographs appeared to show Osbourne hurling her drink over Feldstein, and he was pictured soaking wet as he walked away as Osbourne pointed her finger in anger.

After the alleged incident, speculation arose that Bareilles decided to part ways with Feldstein, who is Jonah Hill's brother, and according to The Hollywood Reporter, she has now moved on to hire Creed, who also handles the career of superproducer Mark Ronson.

Creed is a former A&R executive at Epic Records, where Bareilles is currently signed.

A representative for Bareilles has yet to confirm the hiring.
