It's not really about the Oscars boycott: The feud between Will Smith and Janet Hubert has been going on for decades

It all started on set of the "Fresh Prince of Bel-Air" where Will Smith starred as a young man sent to Los Angeles to live with his aunt, played by Janet Hubert.

Onscreen, the show was a hit but behind the scenes there were lunchtime fights, name-calling and years later, a cast reunion that did not involve Janet Hubert.

"I will never do anything with an a**hole like Will Smith" Hubert vowed 15 years ago.

And she meant it. Hubert recently posted a four-minute long rant on her Facebook page against Smith and his wife Jada Pinkett Smith. Watch the full story with all the details of this decades-long battle here.
