Hilton's $ 500,000 bounty!

Tabloids are offering a tempting $500,000 for the first pictures of Paris Hilton in jail.

The hotel heiress entered Los Angeles' Century Regional Detention Center on Sunday night, after violating her probation following a 2006 drink-driving arrest.

While a mugshot of celebrity prisoner 9818783 has already been printed in newspapers across the globe, U.S. publications are desperate to secure snaps of the star inside.

They hope the huge bounty will entice employees at the prison to take a sneaky shot before Hilton's 23-day sentence is up.
