Brit hires private investigator?    ·    September 2nd, 2007

Britney Spears has reportedly hired a private investigator in California to monitor ex-hubby Kevin as the couple begin their child custody battle.

As Kevin’s legal team builds its case by serving Britney’s friends and her aides with subpoenas to testify in the custody trial, Brit has commissioned Lisa Javoric to dig up dirt on her ex.

Investigators from Javoric’s offices recently hit Las Vegas to watch Kevin’s every move - as the rapper/dancer partied.

In Touch Weekly reports: “The detective watched him intently as Kevin partied in public areas of the hotel. He made a note of everyone who went into his suite.”

Britney hopes the information her investigator gathers will help her discredit Kevin and win her full custody of sons Sean Preston and Jayden James.
