LOS ANGELES, CA (KNX)  -- Paris Hilton denies reports she hacked into Lindsay Lohan's BlackBerry and sent offensive messages to her friends from it.

Hilton suffered a similar disfavor in 2004 when private text messages on her phone were leaked onto the internet.

Lohan's spokewoman Leslie Sloane Zelink tells PageSix.com that perpetrator sent "disgusting and very mean messages that everyone thought were coming from Lindsay. They weren't. We now have lawyers looking into it. Some people think Paris may have been involved because the wording of the messages sounds very familiar."

Hilton's representative Elliot Mintz says, "I'm saddened this happened to Lindsay. I lived through this with Paris two years ago when her Sidekick was hacked into, and the loss of privacy is unbearable. But as for any suggestion that Paris would have anything to do with this, that is silly, untrue and unfortunate."
