Shareef O'Neal: I Got A New Hoops Tutor ... KOBE!!

File this under: TIME HEALS ALL WOUNDS.

A new O'Neal is teaming up with Kobe Bryant to make basketball history ... Shaq's son Shareef ... who says Kobe offered to give him 1-on-1 training this summer ... and he accepted.

Yes, that Kobe Bryant ... the same one Shareef's father used to hate with a white hot passion.

Shareef dropped the news on us while leaving the Four Seasons in Beverly Hills ... saying he ran into Kobe at the All-Star Game in Toronto ... and the Mamba offered to be his hoops Obi-Wan.

"He was telling me I need to train with him ... I'm going to probably start training with him this summer."

The Shaq vs. Kobe beef -- one of the nastiest in sports history -- has cooled in recent years, with the two men gushing about each other in public. But still, didn't see this one coming!

Even though it's all good now ... when we asked Shareef if he'd try to bust Kobe's ass when they eventually play each other, shades of the old O'Neal/Bryant rivalry came back out.

"If we play 1-on-1 ... Imma try to win."
