WANTED: Girlfriend of Public Enemy #1

The FBI is on the hunt for Catherine Grieg, the girlfriend of Public Enemy #1, Whitey Bulger, and they're pulling out all the stops to find her. INSIDE EDITION reports.

She may be the most wanted gangster's moll in American history.

Catherine Grieg is the longtime girlfriend of notorious Boston mob boss, Whitey Bulger, who has just replaced Osama bin Laden as public enemy #1 on the FBI's Ten Most Wanted list.

Bulger is charged with 19 murders, and inspired Jack Nicholson's blood-thirsty mobster character in The Departed.

The FBI has just released a commercial that says Grieg "is wanted for harboring James 'Whitey' Bulger." Public Service Announcements are airing on The View, Ellen, and Dr. Oz- all of which target women- hoping that someone will recognize Bulger's girlfriend.

Catherine Grieg is 60 years old. Mug shots show she's had several facelifts, breast implants, and a nose job through the years.

Grieg reportedly loves dogs, and the former dental hygienist likes to have her teeth cleaned monthly.

The FBI has also plastered a billboard of Grieg and the mobster in Times Square near the Good Morning America studio hoping to spread the word.  

There is a $100,000 reward for information leading to Catherine Grieg's whereabouts.
