Just last night...
Gyllenhaal hit Fox Searchlight's holiday party at the Thompson Hotel in Beverly Hills. He chatted with his Love and Other Drugs costar (and future Oscar cohost) Anne Hathaway as well as Conviction stars Hilary Swank and Sam Rockwell.
He also spent a chunk of time talking with 127 Hours director Danny Boyle.
Meanwhile, Taylor Swift was across the country Nashville hanging with Maroon 5's Adam Levine. The group performed her song, "Mine," during a taping of a CMT Artists of the Year special.
But don't be surprised if we suddenly see the country crooner pop up in Australia. Gyllenhaal leaves any minute now for Down Under to promote Love and Other Drugs.
Wouldn't they look, like, too cute throwing some shrimp on the barbie together?
