Join a live video chat with ‘Mad Men’s Linda Cardellini on Monday

Join Linda Cardellini, Emmy-nominated for her guest turn this season on “Mad Men,” in a live video chat on Monday at 1 p.m. PDT.

Cardellini’s appearance as Sylvia Rosen, Don Draper’s downstairs neighbor, who enjoys (well ... except for the guilt ... and when Sally catches them in the act) a torrid affair with the advertising executive, might have come as a surprise to fans who know the actress from Paul Feig’s coming-of-age cult classic “Freaks and Geeks” or her long stint as nurse Samantha Taggart on “ER.”

But Cardellini has been mixing it up in her career for years (she played Velma in two “Scooby Doo” movies, for crying out loud), proving she’s capable of many, many things, including convincing, kinky hotel room sex with Don Draper.

We’ll talk to Cardellini about her experience on “Mad Men,” working with Jon Hamm and whether she thought it was really necessary to travel to the set (per “Mad Men” creator Matthew Weiner’s orders) in a van with covered windows to keep her appearance on the show a secret. We’ll also be happy to ask your questions. So hit the RSVP button, submit your queries and we’ll see you Monday!
