'SNL' PROMOS: Kristen Wiig and Fred Armisen Order Up Some Promos for This Weekend's 'Saturday Night Live'

Are Garth and Kat back together? Kristen Wiig was joined by Fred Armisen for her Saturday Night Live promos, reuniting the former Weekend Update singing duo. It's fun to see Wiig back on the SNL stage, even though she hasn't even been away for a year. What should fans expect from Wiig during her hosting debut? These promos didn't give away much (besides maybe an appearance by Olivia Newton John?), but chances are Wiig will return to as many of her classic characters as possible.

Check out Wiig's SNL promos after the jump.
