Katy Perry VMA Red Carpet - H 2011

Before Saturday Night Live goes dark for the holidays, it has firmed up plans to bring on Katy Perry for the Dec. 10 episode.

The singer, who previously appeared in 2010 as a musical guest and lampooned her banned Sesame Street segment, will take the stage on her own for her first time as host.

Unlike many pop stars, however, Perry won't be doubling as the musical guest. NBC also announced Swedish singer Robyn will serve as the night's performer.

Perry, who recently ended her California Dreams tour, is not a complete stranger to acting. She appeared in an episode of How I Met Your Mother earlier in the year and lent her voice to Smurfette this summer's feature adaptation of The Smurfs.
