Ashley Greene is bringing some bite to “Pan Am.”

With shooting on the “Twilight” vampire movies over, Greene’s been spending her free time filming scenes for her upcoming guest starring role on the ABC drama.

The 24-year-old — decked out in the requisite white gloves, dainty purse and swinging ’60s coat — was spotted in Gramercy Park, locking lips on set with Michael Mosley, who plays First Officer Ted Vanderway.

Greene was cast as the airplane pilot’s love interest in November.

Despite plenty of hype, “Pan Am” has had a rocky debut season.

After ratings rapidly declined in the fall, ABC opted to give the series about ’60s flight attendants and pilots a truncated 14-episode season, but insists that it has not yet been canceled.
