Jamie Foxx gets jolly for Christmas in his promo for “Saturday Night Live.” The actor-singer, who stars in Quentin Tarantino’s western Django Unchained, returns to host the show for the second time this weekend with musical guest Ne-Yo. In the series of funny promos, Jamie trades jokes (and Christmas sweaters) with “SNL” cast member Jason Sudeikis while standing in front of the famed Rockefeller Center Christmas tree in NYC.
