Who? Colombian actress.
Real? The tape exists and circulates widely.
Ana Maria Abello is a fairly obscure celebrity. IMDB has a few listings for TV appearances. Her most famous role appears to have been as Adoración in the telenovela La Venganza. Google brings up mostly references to the sex tape, not to her mainstream acting career.
The Ana Maria Abello sex tape runs five minutes. It shows two Latin American college-age kids having sex on a bed. They take turns moving and holding the camcorder while running through a few sex positions. They’re both very attractive and enthusiastic, but most of the video is too blurry and jerky to enjoy (unless motion sickness turns you on).
Even though it circulates under the title “Ana Maria Abello sex tape”, I have no idea whether the girl is really Ana Maria Abello.
