EXCLUSIVE DOCUMENT: Read The Legal Letter Jeremy London Sent His Brother's Girlfriend!

Jeremy London was so angry that his twin brother Jason and his mother gave an interview doubting the Mallrats star's kidnapping story that he sent a legal letter - and RadarOnline.com has exclusively obtained a copy.

Jeremy and Jason are not close and when Jason and his mother spoke out on the E! channel, Jeremey took action, taking aim at Jason's girlfriend Sofia Karsten.

“You have been granting unauthorized interviews,” Jeremy’s lawyer wrote, although it is unclear why the interviews would have to be authorized. The letter goes on to state that Jeremy’s publicist must approve all interviews, but again does not say why.

About the interviews, Jeremy’s lawyer states: “The information you are providing is false and your behavior is reckless and could potentially harm the reputation of my client.”

“This is to advise you that if you do not immediately cease and desist from engaging in any type of interviews with regard to Jeremy London, we will seek an immediate injunction against you in a court of law to prevent you from granting interviews and from exploiting the personal life of Jeremy London.”
