Today's talk you might've missed:

• Jim Parsons is ending your long wait to see him host "Saturday Night Live" on March 1. We can't wait for the Sheldon riffs!
• Speaking of "SNL," it's not going to be all alums all the time on Seth Meyers' "Late Night." While he will have Amy Poehler on as his first guest and Fred Armisen as his band leader, Meyers' first week will also include Vice President Joe Biden, Kanye West and Lena Dunham. [THR]
• The Academy Awards will feature a performance from basically everyone except Scarlett Johansson. U2 and Karen O. have joined the lineup to perform best original song nominees "Ordinary Love" and "The Moon Song," respectively. (Karen O. wrote "The Moon Song" for "Her," so it does make sense that she'll be the one to perform it rather than ScarJo, who sang it in the Spike Jonze film.)
• The CW sees no reason to get rid of "Arrow," "The Vampire Diaries," "Reign," "The Originals" or "Supernatural," so they've all been renewed for another season.
• Bruce Jenner may or may not be done with "Keeping Up with the Kardashians," depending on which Kardashian you've been keeping up with. [TMZ/People]
• Got a spare $150,000? Katherine Heigl, Hollywood actress who we'd think should be getting residual paychecks from "Grey's Anatomy," wants to borrow some bucks to get her new movie made. [EW]
