Jennifer Hudson's ego is growing as fast as her rep as a diva in training.

The Oscar-winning former "American Idol" contestant, according to Page Six, called the day before the Soul Train Awards show in Los Angeles and told them "she couldn't make it," says a source. But "Soul Train" impresario Don Cornelius wasn't having any of her swanny behavior and called Davis, who told Hudson, "Get your ass out to L.A." She obliged.

This comes after her well publicized diss of 'American Idol' after winning the Oscar for best supporting actress. She failed to credit the show for giving her her start, and when asked about it, dissed the show royally by comparing it to working at Burger King.

Jen needs to stick to her "aw shucks" routine if she wants to keep going up the way she has been. She hasn't been around Hollywood enough or paid enough dues to deserve a diva attitude at this stage in her game.
