Nothing says holiday cheer like a terrorist in a Christmas-y sweater.

“Homeland” thesp Navid Negahban was a magnet for guests on Monday night at Showtime’s holiday soiree, held at a private BevHills residence with a million-dollar view of L.A.

A slew of Showtime stars made the rounds at the party, which spilled out into the backyard pool area (even in December), but it was the smiley Negahban who grabbed all the attention for his role as diabolical terrorist Abu Nazir on the pay cabler’s red-hot political thriller.

Given the momentum of “Homeland,” Showtime honchos Matt Blank, David Nevins, Gary Levine and others were understandably in a felicitous mood. The evening also offered a partygoers a glimpse of a mini-“Friends” reunion as Matt LeBlanc, star of comedy “Episodes,” and Lisa Kudrow, star of “Web Therapy,” huddled at a table and shared laughs.
