UFC champ Jon "Bones" Jones says he doesn't believe the allegations against Bill Cosby -- telling TMZ Sports the actor always seemed way too classy to be a rapist.
Jones was at LAX Friday when he explained why he was on Team Bill -- "I've never met him, but from what I've seen he seems to be a class act. I kinda grew up admiring him."
In fact, Jones also joked that Cosby was such a huge star, he wouldn't need to rape women -- he could have anybody he wants.
Still, Jones adds ... "I hope [the allegations are] not true."
