Last week, we caught a nostalgiatastic snapshot of almost the entire Fresh Prince of Bel-Air cast, reunited for an appearance at Karyn Parson's (Hilary) charity event. Noticeably absent were both Aunt Vivs.

While we can't account for the second, longer-running Aunt Viv, we have an idea of why the first one, Janet Hubert, wasn't in attendance. She just HATES Will Smith, and doesn't voice her distaste in the most diplomatic fashion.

Hubert told TMZ recently, "There will never be a reunion ... as I will never do anything with an asshole like Will Smith," Hubert said.

Considering how phenomenally well-liked Smith has managed to be over the course of his career, it sounds like Hubert is just a little peeved that she was clipped after contract negotiations fell through. She went on to say, "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."

You heard it from TMZ first - Will Smith doesn't know the word "an apology."

Heady stuff.
