Model-turned-reality star Janice Dickinson has taken aim at her ex-boss Tyra Banks after the former Victoria's Secret stunner suggested she was jealous of her success in an interview.

Dickinson was fired from Banks' beauty contest America's Next Top Model amid reports the two former catwalk stars never got along.

Banks has not spoken about her decision to get rid of the ageing supermodel, but was asked about things Dickinson has said about her in a recent TV news interview.

When quizzed by interviewer Cynthia McFadden whether Dickinson and fellow sacked judge Paulina Porizkova were jealous of her, Banks refused to answer, but smiled and replied, 'Is that what you think?'

And the veiled hint has made the older model seethe.

In a new interview on TV news show The Insider, Dickinson sarcastically says, "Damn right I'm jealous... Everybody's jealous of the great Tyra."

But she insists she has no issues with the way she was dumped from Banks' hit show: "There's no problem - Tyra hires people, uses them and then boots them out and then hires the next person - I guess for a nominal fee."

But she does take issue with her ex-boss' claims that she's not much of a diva, adding, "She is the biggest diva on the planet next to me."
