Paris Hilton has a message for her fans: don't drink and drive.

Writing in a July 3 entry on her MySpace web page, the 26-year-old celebrity heiress said "Happy 4th of July everyone, and remember to be responsible and have a designated driver!"

Hilton was released from jail last week, after spending 23 days behind bars for violating her probation in an alcohol-related reckless driving case. She has since claimed to be changing her hard-partying ways.

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

Paris Hilton did a series of post-jail interviews, including CNN's "Larry King Live," then left for a holiday on the Hawaiian island of Maui.
