It’s already pretty clear that Bam Margera has very little fear but to get into a fight with a pro boxer?  That’s probably not the best idea.  To make matters worse the fight was allegedly over a female.  Read more after the jump.

Bam Margera got into a full on street fight in Australia this week with an UNDEFEATED PRO BOXER … and TMZ has learned it was all over a girl.

Sources close to the “Jackass” star tell us … Bam and a close lady friend were hanging out in Adelaide, Australia … when the two were confronted by the chick’s ex-BF … who just happens to be an undefeated featherweight boxing phenom.

We’re told the two men exchanged words … and then fists began to fly.  Sources tell us … Bam “held his own” … and “didn’t get hurt that bad.”

We spoke with cops who told us no arrests were made.
