Nine years after she first pulled double-duty on Saturday Night Live, performer extraordinaire Jennifer Lopez will take on the task again at the late-night variety show in February and alum Tina Fey is also set to host again in April. NBC announced Thursday that Lopez will be both the musical guest and host when SNL returns February 27. She'll be promoting her return to silver screen with The Back-Up Plan as well as Love, her first album in three years. Both are slated to be released in April, which is when SNL's former head writer, Tina Fey, will take on hosting duties at her old stomping grounds. The Golden Globe-winning actress will be plugging Date Night, her upcoming comedy with Steve Carrell, and plans to reprise her spot-on impression of former Alaska governor Sarah Palin. "It's inevitable that we'll try it, at least," the 30 Rock star told the AP. "We'll see if it makes it to air."
