Matthew Knowles says he BALLED UP Kobe Bryant when they faced off in some 1-on-1 twenty years ago ... and he'll gladly kick Kobe's ass again if Mamba wants to run it back!!!
We spoke with Beyonce's dad after he unearthed video from the set of the Destiny's Child "Bug A Boo" video -- where he took on Kobe while wearing dress pants, dress shoes and a Polo shirt.
Matthew actually got a bucket on Kobe -- and Knowles says it was ALL SKILL, BABY!
