The singer, 27, will host for the first time on Dec. 10, TVGuide.com has confirmed. Robyn — who is currently touring with Perry — will be the musical guest that evening.
Steve Buscemi will host for his second time on Dec. 3 with The Black Keys slated to perform. As previously reported, Jimmy Fallon will return to his old stomping grounds to host SNL for the first time on Dec. 17. Michael Bublé will perform on the show, the series' last episode before Christmas.
Perry previously appeared as the musical guest in Sept. 2010. She made headlines during the episode when she appeared in a sketch wearing a cleavage-bearing Elmo T-shirt soon after a Sesame Street skit she appeared in was cut because of complaints about her low-cut top.
Perry's husband, Russell Brand, hosted the show back in February.
