Who? Reality TV personality.
Real? Yes, she performed in online porn before her TV break.
Brandi Moran was a contestant on the first season of Rock of Love with Bret Michaels, where she was known as Brandi M (to distinguish her from rival Brandi C). She ended up finishing fourth on the show. She later appeared on Rock of Love: Charm School, which she won.
In December 2008, around the time of the Rock of Love: Charm School finale, Brandi M’s past in online porn came to light. She performed in hardcore scenes for websites Amateur Facials and Purely Pamela (both now offline).
Her scene for Amateur Facials now circulates online as the Brandi M sex tape. The version I’ve seen runs twelve minutes, but there may be a longer version. She takes a shower, then kneels in the tub and sucks a faceless dude’s cock for several minutes. As you might have guessed, the dude jacks off on her face at the end.
