Lindsay Lohan's best friend and former manager, Jenni Muro, is fronting a cause close to her heart -- substance abuse.

Muro has partnered with a team of professionals (the owner is the former co-owner of Wonderland) to host the first annual Wellness Event, taking place saturday Oct. 23, at the One80 Sober Living House in Beverly Hills.

The event will feature speakers, health and spiritual activities, food, entertainment and a raffle.

Located on the grounds of an estate once owned by Elizabeth Taylor at the top of Benedict Canyon, the center devotes itself to educating and saving the lives of those battling substance abuse.
