• Jake Gyllenhaal was cracking up and laughing with pals during a lively night at West Hollywood's Chateau Marmont – but the actor gave special attention to one woman: Olivia Wilde. The two were very flirty, an onlooker says, acting "touchy-feely." Says the onlooker: "At one point, he had his hand on hers." Still, the two weren't overly affectionate with each other. "Olivia was very cool," the onlooker says, "and wasn't fawning over Jake but seemed to like the attention he was giving her." Alas, at the end of the evening the two went their separate ways. As for their relationship, the actress's rep tells us they're just friends.

• Also at the Chateau: Ashley Olsen, who was seated at a large round table in the back of the patio with her friends. "She seemed to be in a great mood," a fellow reveler says, noting that the group was low-key and wasn't "creating any sort of commotion" during their short visit.

• Mom-to-be Lindsay Price and Curtis Stone snuck in unnoticed to a performance of Fuerza Bruta: Look Up in N.Y.C. Once inside, the two were super affectionate and sweet together and seemed to really enjoy the performance. Afterward, the two were eager to stay and meet the cast and snap pictures.

• Whitney Port stopped by the John Frieda Destination: Style Mobile salon in L.A. to get her hair touched up. The reality star was with her little sister and was super upbeat during the appointment.
