Sara Bareilles fired her manager Jordan Feldstein after a heated, water throwing fight Feldstein got into with Sharon Osbourne.

Jordan Feldstein, whose clients include Maroon 5 and Robin Thicke, was fired by Bareilles on the day of the Grammy’s for a fight he got in with Osbourne at Clive Davis’ pre-Grammy gala the night before, according to The Hollywood Reporter. Feldstein, who is Jonah Hill’s brother, originally started fighting with Kelly Osbourne reportedly over comments the manager made about her brother Jack and his wife. Sharon quickly followed suit where the fight between the two managers erupted. Bareilles, who was sitting with her manager at the time, fired Feldstein the following day.

E! Online reported that a source told them the two have had a long running feud.

This is not the first of tabloid fodder Feldstein has seen recently, having married Francesca Eastwood, Clint Eastwood’s daughter, back in November, which after only a week, was annulled.

There is no word on who Bareilles will now be managed by.
