While American Idol 3 winner Fantasia Barrino gears up for her next single release, also on her agenda is another post-“Idol” TV gig. After playing Aretha Franklin on “American Dreams” and appearing on “All of Us” last year, she’s returning to the small screen for a guest role on The Simpsons. “When you do ‘The Simpsons,’ that’s major,” Fantasia said. “That’s like a big-time cartoon that everybody watches. When they called me, I was like, ‘Of course I’ll do it!’ I played Clarissa and I’m singing up against Lisa [in an ‘American Idol’-like competition], and she wins. I was kind of hurt about it and I had to do this big crying scene and I was like, ‘How am I going to cry?’ And I started having flashbacks of how my baby cried all the time when I’m at home, so it wasn’t too hard.” No details on this episode have been released yet but it could possibly air at the end of this season or the beginning of the next.
