Mary-Kate Olsen Posts Party Pictures on Website 8/11/08

Actress Mary-Kate Olsen has fuelled her party-girl image by reportedly posting a series of rowdy pictures on a social networking website.

The star is shown in an album of photos partying hard with pals after failing to block users she has yet to befriend on her Facebook.com profile page.

According to the New York Daily News, the actress has created a profile under the name Katie Olsen - and the profile is open to anyone in her New York-listed network.

Just last week (begs04Aug08), Olsen escaped having to testify in front of a grand jury in the mystery prescription drug overdose that led to actor Heath Ledger's death in January (08), after prosecutors closed the case due to lack of evidence.

Olsen's name was dragged into the case because the masseuse who found Ledger dead called the former child star before contacting the emergency services.
