At a meeting Thursday of the Television Critics Association in Beverly Hills, Sidibe described herself as a "middle-of-the-lane, very normal" person who'd planned to be a receptionist.
The 27-year-old Sidibe said it's been a "strange year" that's included her Academy Award nod for her role as a teenager who rises above abuse in "Precious: Based on the Novel `Push' by Sapphire" and her co-starring role in Showtime's "The Big C."
The comedy-drama stars Laura Linney as a schoolteacher confronting a terminal-cancer diagnosis. Sidibe plays a smart-alec student.
"The Big C" debuts 10:30 p.m. EDT Monday, Aug. 16, on Showtime.
