Casey Johnson, the heiress who was arrested on Monday on charges of grand theft, has been threatened with a restraining order from the model she allegedly stole from.

The troubled 30 year old, whose family own the Johnson & Johnson pharmaceutical empire, was taken into custody after Los Angeles police searched her home and allegedly found items belonging to model Jasmine Lennard, including jewelry and designer clothing.

Lennard, who was once romantically linked to Simon Cowell, claims she had been trying to help Johnson deal with a substance abuse problem when the heiress became infatuated with her.

She says, "I tried to get her off drugs and alcohol. I tried to get her into a 12-step program. I tried to help take care of her daughter and gave her money. I am the only person who helped this girl. I believe she was obsessed with me and thinks in her mind we had some kind of affair. That is not the case. She breaks into my apartment, gets into my bed, has a shower in my bathroom, then takes everything."

And the brunette, the daughter of former Bond actress Marilyn Galsworthy, insists she will be taking legal action to ensure Johnson stays away from her.

She tells RadarOnline.com, "The first thing I'm doing this morning is getting a restraining order. I've had a hell of a lot of patience and compassion for this woman and she just hasn't treated me right. Casey is an evil girl. She's going to be full of vengeance and try to attack me in any way she can."

Johnson was released from jail in Van Nuys, California on Monday on $20,000 bail.
