Gwen Stefani signs on with RED to promote AIDS documentary

Gwen Stefani has joined forces with (RED) to lend her voice to the cause of spreading the word about an upcoming HBO film entitled The Lazarus Effect, which documents an inexpensive AIDS treatment which can bring those dying of the disease back to a healthy state within forty days of treatment. Also signed on to help spread the word about the film are Penelope Cruz, Orlando Bloom, Iman, Hugh Jackman, and Don Cheadle. The Lazarus Effect, which will debut on May 24th on HBO, is directed by Lance Bangs and executive produced by Spike Jonze. A trailer for the movie can be viewed here

(RED) is a charitable effort spearheaded by U2′s Bono and others aimed at encouraging corporations to offer special red versions of their existing products with a portion of the sales going to charitable causes.

Gwen Stefani rose to fame as lead singer for No Doubt and has also since launched a successful solo career. She’s married to Gavin Rossdale from Bush, which we mention because we interviewed him at the start of his solo career. Gwen Stefani is expected to release a new album with No Doubt in 2010.
