Charlie Sheen's former 'goddess' Bree Olson is using her 15 minutes of fame to give a porn star rock band a boost - she has signed on as the group's manager

The sexy blonde is helping Tight - featuring adult actresses Alicia Andrews and Kelley Jean - land gigs and navigate the music business.

She says, "The biggest challenge a porn star band faces is being taken seriously. These are very talented musicians but not everyone is willing to give them a chance."

Her efforts will be featured on a new mockumentary DVD, which will hit stores next month.

The band has already been given a big boost by shock jock Howard Stern - after it won his XXX Factor talent competition back in April.
