Irony is alive and well and ready for its closeup at the Oscars. E! has announced that Jennifer Holliday, who may or may not still be extremely bitter about being passed over for the role of Effie in the "Dreamgirls" film, is going to provide live entertainment during its six-hour "Countdown to the Red Carpet" special. She's going to sing "And I'm Telling You, I'm Not Going" -- Effie's showstopper that marks the beginning of a steep personal and professional decline. Jennifer Hudson is picking up the hardware at nearly every awards show and is in the elite Oscar nominees club, but Holliday, who originated the role on Broadway, is digging her heels into the red carpet.
