She already had a sing-off with Dreamgirls costar Beyoncé at the Academy Awards, but there's another R&B diva Jennifer Hudson is planning on teaming up with on her upcoming debut album: Whitney Houston.

Though recording together isn't official yet, the two powerhouse singers have already met several times. "She's been one of my biggest supporters through everything," the Oscar winner said backstage at the NAACP Image Awards, where she received a best supporting actress honor for her Dreamgirls role. "I love Whitney, she's amazing and she's the reason I wanted to become a singer. I used to come up with duets between me and Whitney and sing both parts! I'm so serious."

What else is on Jennifer's full plate? A role in the upcoming Robert Redford-directed biopic about baseball legend Jackie Robinson. "It tells of greatness and our history; that means something to me," she told Access Hollywood in an interview airing Monday.
