Who? Brazilian actress/model.
Real? No, just fakes starring a lookalike pornstar.
Juliana Paes is a very successful soap opera actress and model in Brazil. Her career started around 2000. She posed nude for and appeared on the cover of Brazilian Playboy in 2004.
Juliana Pires is a Brazilian pornstar who somewhat resembles Juliana Paes and who apparently chose her porn name to trade on that resemblance. Her career started around 2003.
In 2007, street vendors in Brazil started hawking a hardcore porn DVD entitled Juliana Paes – Antes Da Fama (“Juliana Paes Before She Was Famous”). The DVD box cover used a topless photo of Juliana Paes from her Playboy pictorial. The back cover used more Playboy shots plus some bikini pics of Juliana Paes from a beer ad. The DVD contained a hardcore porn scene starring Juliana Pires, the lookalike pornstar.
Many tube sites, download sites, torrent sites and forums still hype this video, or other other Juliana Pires porn scenes, as a Juliana Paes sex tape. It’s not. Juliana Paes has never done porn (at least nothing harder than the Playboy nudes) and she doesn’t have a sex tape.
