Justin Bieber's bodyguard sues star for alleged fight: Report

Baby, baby, baby -- ow!

A former bodyguard for Justin Bieber claims in a lawsuit that the 18-year-old pop star assaulted and berated him.

Moshe Benabou, who worked for the "Boyfriend" singer between March 2011 and October 2012, is seeking unspecified damages for assault and battery and more than $400,000 in overtime, TMZ.com reported Thursday.

The singer's representatives dismissed Benabou's claims, and telling the gossip site that the bodyguard is nothing more than a "disgruntled employee looking for money."

TMZ reported that Bieber fired Benabou, a former Israeli soldier, because he lied about protecting other celebrities, including Justin Timberlake.

Last February, Benabou was caught on camera beating up a photographer at LAX Airport.
