Brooklyn, NY native Angelina Armani (aka Arianna Armani, Ariana Armani) was never interested in porn until she realized it was a way to get paid for her exhibitionistic urges. Her beauty and 5'10" stature meant that she was able to pursue modeling as a teen, but by age 20 Angelina decided to try XXX. Angelina soon got noticed thanks to red carpet appearances and exposure through a Mixed Martial Arts blog, and in October 2008 she signed a Digital Playground contract even though she had never filmed with them before, on the strength of her dazzling appeal at the Pirates II premiere. Her first Digital Playground picture, Angelina Armani: the Big Hit, was fast-tracked so she could promote it at the Adult Entertainment Expo in January 2009. As a Trophy Girl at the AVN Awards that same month, Angelina's visibility in the industry grew even more. While under contract with Digital Playground, Angelina filmed eight movies. She and the company parted ways in April 2009 as Angelina expressed interest in branching out to work for other studios. Two of Angelina's highest profile roles since becoming a free agent have been in Not Monday Night Football XXX and Pussy Eating Club 1. She won her first award (Night Moves' Best New Starlet) in 2009 and was nominated for New Starlet awards at the AVN and XBIZ Awards the following year.

Outside of performing in adult film, Angelina has appeared on horror fan websites (she's a horror fan herself) and has been an impressive red carpet interviewer for adult industry events. She also filmed for an HBO/Funny or Die web miniseries called "Designated Driver" prior to leaving Digital Playground.
