Watch: January Jones’ Smiley ‘SNL’ Promo

Rare is the occasion when January Jones’ Betty Draper cracks a smile on AMC’s ‘Mad Men,’ but in the promo  for her upcoming hosting gig on ‘Saturday Night Live,’ Jones is not only grinning, she’s singing, too!

Check out the four clips below, where Jones shares the stage with co-star Elisabeth Moss’ real-life hubby Fred Armisen.

The best out of the bunch? Armisen’s deadpan response to Jones’ question, “Do you watch Mad Men?”

“No no no. God no. It’s gross,” he jokes. So much for spousal support!!

Jones is the second ‘Mad Men’ cast member to host ‘SNL,’ following in the footsteps of her on-screen soon-to-be ex-husband, Jon Hamm, who took up the post last October.

Let’s hope her appearance comes with a handy  “Betty Draper Guide (to dumping Don Draper?),” as well!
