Kobe Bryant Dines With Michael Jordan Over a Steak Dinner In Beverly Hills

Kobe Bryant and Michael Jordan had a private dinner together in Beverly Hills last night -- eating at one of the fanciest steak joints in town.

The Mamba and His Royal Airness -- who have been friendly for a while -- dined together in a private room at Mastro's Steakhouse.

It's unclear how long the dinner lasted ... or who paid.

It was a celeb-packed day for MJ -- who had lunch with Mark Wahlberg just hours before. Mark paid for that meal telling us it's the least he could do for Michael since Jordan always hooks him up with sick shoes.
