Paris' PSA: Don't Drink And Drive

Paris Hilton is back from vacation and has public service announcement of sorts for her fans: don't drink and drive.

"Happy 4th of July everyone, and remember to be responsible and have a designated driver!" the heiress writes in a blog entry on her MySpace Web page Tuesday.

Hilton, 26, was released from jail last week after spending about 23 days behind bars for violating probation in an alcohol-related reckless driving case. The notorious party girl has since touted a new beginning - one that she says won't include going out as much.

"The past month has inspired me to move forward with some exciting new projects, so I will keep you all posted," she writes.

After getting out of jail, Hilton did a series of interviews, including one on CNN's "Larry King Live," then skipped town for some rest and relaxation in Maui.
