LiLo, Paris Jealous of Jon and Kate

With Jon and Kate Gosselin dominating the tabloids, party girls like Lindsay Lohan and Paris Hilton are doing anything they can to get back in the spotlight. “Lindsay and Paris hate not being on the covers of weeklies,” a source tells the New York Post. “That's why Lindsay has been causing so much havoc and pulling these antics. And why Paris had a big blow-up with Doug.”

To that end, LiLo denies accusing Justin Timberlake, via Twitter, of cheating on Jessica Biel, E! adds. “I don’t twitter about my personal life! Let alone, someone else’s life!” she posted, seeming to forget all her previous oversharing posts about on-again-off-again love Samantha Ronson. Lohan accused a “creepy” hacker of accessing her account to post the tweet and said, “I'm tired of changing my password every other day!” (More Lindsay Lohan stories.)
