A slew of big name stars -- Leonardo DiCaprio, Nicole Kidman, Steve Martin, Robert Redford and Warren Beatty -- and the smash TV show Downton Abbey were all victims of the notorious hacker Guccifer, Breaking Celebrity News has learned.

The Smoking Gun reports that Redford and Beatty's phone numbers were stolen by the hacker, as were Kidman and DiCaprio's e-mail addresses.

A script for Downton Abbey's season four finale was snatched six months prior to the episode's broadcast, according to the report.

Guccifer's antics previously made headlines after the hacker infiltrated the personal accounts -- including, in some cases, confidential financial statements, e-mails, and contact lists -- of political figures such as Colin Powell, Bush and Rockefeller relatives, and members of President Barack Obama's administration. Other prominent personalities hacked include tell-all scribe Kitty Kelley, Star 80 beauty Mariel Hemingway and John Dean, a former Richard Nixon aide.
