Will Smith is still an egomaniac and has not grown up his co-star says.

Will Smith has been branded an "egomaniac" and an "asshole" by a former 'Fresh Prince of Bel Air' co-star.

Janet Hubert - who starred as the original Aunt Vivian when the show started in 1990 - was missing from a recent cast reunion, and said she wouldn't want to be included because she is still upset at being fired, blaming Will's personally.

She told TMZ: "There will never be a reunion - as I will never do anything with an asshole like Will Smith.

"He is still an egomaniac and has not grown up. This constant reunion thing will never ever happen in my lifetime unless there is an apology, which he doesn't know the word."

Janet, 55, was replaced on the show by Daphne Maxwell Reid in 1993, and blames her departure from the comedy series on the fact she wasn't prepared to suck up to Will, who had become the star of the show aged just 22.

Will, now 43, has previously said he believes Janet had a bad attitude, and refutes the idea he was personally responsible for her departure.

He said in a radio interview shortly after she left: "Janet said once, 'I've been in the business for 10 years and this snotty-nosed punk comes along and gets a show.' No matter what, to her I'm just the Antichrist."
