Jets quarterback Mark Sanchez seemed to take a shine to actress Jamie-Lynn Sigler at a Tribeca Film Festival event. At a private screening of “Keep Surfing” presented by LG at the Tribeca Grand penthouse Monday night, Sanchez and Sigler “chatted and laughed while sitting together on the couch during the film, and they even went upstairs to the terrace to take in the view.” Meanwhile Sanchez, who sipped water all night, politely rebuffed advances of other women in the room.
