Kirsten Dunst and Garrett Hedlund took to their bikes for a ride near her LA home yesterday. They practically matched in their gray sweats, but the outing wasn't all about exercising — Kirsten also put posters up to publicize her cat's disappearance. Kirsten and Garrett are together in California after spending a few days last month in Utah. They headed to Park City for the Sundance Film Festival premiere of Bachelorette, Kirsten's new dark comedy with Isla Fisher, Lizzy Caplan, and James Marsden. Garrett skipped the red carpet, but he and Kirsten were seen getting close at the afterparty. It seems the couple got together at some point last year after meeting on the set of On the Road. Both Kirsten and Garrett star in the big screen adaptation of the classic Kerouac novel, which also features Kristen Stewart and Tom Sturridge.
