Joaquin Phoenix has a new girlfriend ... emphasis on "girl."
The 39-year-old actor was recently seen touring Rome with a cute blonde on his arm -- and, at 19, she's less than half his age!
Joaquin's new piece is teenage DJ Allie Teilz, who, despite her young age, appears to have been working in the entertainment biz for a while now.
"When I was younger I used to work production for arena shows in Vegas and Palm Springs, and I did artist relations for pop stars," she said in a recent interview with Bullett magazine. "On Thursdays after school I would go from school to the airport, fly to Vegas, work the shows from 6am Friday until Sunday at 2am, before school."
"I had a complete double life and lied about my age," she continues. "But I was really getting involved in the music world and starting to meet people."
The two have apparently known each other for some time, as she appeared in the 2008 music video Joaquin directed for Silversun Pickups, "Little Lovers So Polite."
