Jake Gyllenhaal dating graduate student?

Actor Jake Gyllenhaal is reportedly dating a 26-year-old graduate student.

The Brokeback Mountain star was photographed walking arm-and-arm with a mystery woman in New York City on 9 November (12) and she has since been identified by bosses at the National Enquirer as Iranian Mahsa Jafarian.

According to the publication, she is currently enrolled in a master's degree program at a college in the Big Apple and met the Hollywood hunk on a train in September (12) - and they have been hanging out ever since.

A source says, "He asked for her number and gave her a call a few days later to ask how she did on an exam she'd told him about... Mahsa thinks Jake is intelligent, well-rounded and a perfect gentleman - and she's completely smitten with him."

Gyllenhaal's former leading ladies in real life include blondes Reese Witherspoon, Kirsten Dunst and Taylor Swift.
