Lindsay Lohan and Paris Hilton�s feud has stepped up to unprecedented levels with the actress by suggesting Paris is responsible for hacking into her phone.

The Just My Luck star has recently suffered the ignominy of her Blackberry internet cell phone being illegally accessed and obscene messages could be sent to friends.

And Lohan�s aide has suggested that aspiring-rapper Paris may be the person behind the telephone trouble.

Leslie Sloane says that �disgusting messages� have been sent in her client�s name, adding, �Some people think Paris may have been involved because of the wording.�

However, Hilton�s people have immediately denied the allegation, explaining that Paris was so hurt when her own phone was hacked into a couple of years ago and compromising pictures and photos were stolen she�d never contemplate doing it to anyone else � not even her worse enemy.

Elliot Mintz tells the New York Post, �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."

The two ladies have a big history between them, with the latest of a long line of incidents occurring earlier this week when Paris sneakily made fun of Lindsay behind her back at a party in Malibu.

It�s all a bit high school, isn�t it girls?
