Janet Hubert and Will Smith

Bummed that Janet Hubert — the original Aunt Viv — wasn't at last week's Fresh Prince of Bel-Air reunion? Well, don't count on seeing her at any future ones either. The actress tells TMZ that she's still mad at NBC and Will Smith over her firing 18 years ago.

"There will never be a reunion ... as I will never do anything with an a--hole like Will Smith," she tells the site. "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."

Hubert and Smith had a notorious falling-out after she was fired and replaced by Daphne Maxwell Reid following the third season in 1993. According to Hubert, NBC tried to reduce her episode count and slash her salary in half, and then let her go when she refused the terms — a move she believes Smith was behind.

Smith has denied Hubert's claims and told an Atlanta radio station at the time that Hubert's bad attitude led to her dismissal. Hubert was pregnant during the third season and admitted to being "moody" at work, but said she was not part of the tension on set.

"I can say straight up that Janet Hubert wanted the show to be The Aunt Viv of Bel-Air Show because I know she is going to dog me in the press," Smith said then. "She has basically gone from a quarter of a million dollars a year to nothing. She's mad now, but she's been mad all along. She 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."

Smith has yet to respond to Hubert's latest comments.
