Last night, Jake was on hand to support Michelle when her latest movie My Week With Marilyn premiered during the New York Film Festival.
Although Gyllenhaal skipped the carpet during the afterparty at the Hudson, he hung tight with Michelle inside the soiree.
But it was another guy who was her actual date for her big night!
"Michelle arrived hand-in-hand with her director boyfriend Cary Fukunaga," a source tells me. "The two stayed close to each other throughout the night, parting when he went to the bar to get them cocktails."
Jake, who is the godfather to Michelle's daughter Matilda, her offpspring with the late Heath Ledger, was also on hand to toast Michelle at the Dior- and Grey Goose-sponsored afterparty, and was spotted talking and laughing with Michelle.
And we gotta say, we'd have been hanging with him, too. He looks great. Check out his specs and scruff that Jake's been rocking lately.
Still, it wasn't all fun and parties for the actor this weekend. On Saturday, he was spotted jogging through Central Park.
But Michelle wins for the busiest night. After she helped introduce the film, she ducked out of the bash early to catch a flight to Detroit to make a 4 a.m. calltime for yet another movie she's starring in.
All in a day's work!
