This is strictly a rumor, but we hear that another person to join Greg (Hollywood) in the cast is Brianna (Hollywood). Brianna Taylor, is a 20 year-old aspiring singer from Warminster, PA. Rumor has it that she's on the next season of the Real World.
Brianna appeared on Season 5 of American Idol and she made it to Hollywood. She's definitely an aspiring singer, so she fits the mold that the casting directors were looking for in this twentieth season. Her MySpace profile has also been abandoned for the time being. Meaning, either she's in a locale that doesn't allow computers or she may not be allowed to be using a computer.
This doesn't entirely make sense, as each cast has had internet access in the past. This would also mean that the cast is already being filmed or is in the process of filming as we speak. So far, no word from the bowels of Hollywood.
Update: Since last week, cast and camera crews have been spotted all over Sunset and Gower. It seems that Columbia Square is indeed the site of the Real World 20 house.
