Josh Hartnett and Rihanna recently filmed a segment for TRL and must have really taken a shine to each other. Rumor has it that Josh, 29, and Rihanna, 19, are now sort of dating.
That could mean anything from a one night stand to shopping for mutual real estate. Hey, things can move fairly quickly in Hollywood. If any of the summer gossip is true, these two have both been keeping busy in the romance department.
While Rihanna has been spotted out on the town lately with Shia LaBeouf, Josh passed his time with actress Scarlett Johansson and model Helena Christensen.
