Jake Gyllenhaal was spotted out at the Sundance Film Festival this week, shaking hands and literally kissing babies.

But instead of promoting his own filmmaking, Gyllenhaal came to support his mom, Naomi Foner Gyllenhaal and her directorial debut, "Very Good Girls."

Starring Dakota Fanning, Lizzie Olsen, and Boyd Holbrook, the gang premiered the flick Tuesday in Park City, Utah, and headed to Main Street's NK lounge, a pop-up space from New York nightlife architect Nur Khan.

Gyllenhaal, who commuted from the Georgia set of his new film "Prisoners," donned dark threads and denim for the fete and raved about his mom's work, according to one partygoer.

The 32-year-old mulled over the flick with the likes of Francesca Eastwood — this year's Miss Golden Globe and still main squeeze of photographer Tyler Shields as far as we know — along with Fanning.

But back to the family affair: Not only was Gyllenhaal's godmother, Jamie Lee Curtis, in attendance, the actor also spent a "large portion" of the evening cradling and playing with a baby that was rolling with the group.

Yet more cuddling: Lizzie Olsen (Mary-Kate and Ashley's talented younger sibling) never strayed far from her beau and co-star Holbrook, who navigated the soiree with an ever-present hand on the small of her back.

The film pits high school best friends played by Olsen and Fanning against one another in attempts to win the affection of Holbrook's character. Naomi is best known as a screenwriter, for films like Halle Berry's "Losing Isaiah."
