Chris Brown Injured In Bar Photos and Video

 We're told there were no critical injuries ... just bumps, bruises and lacerations. No arrests were made.

After the fight, Brown tweeted a photo of his injury ... along with the message, "How u party wit rich n**** that hate? Lol... Throwing bottles like girls? #shameonya!."

The photo and the message have since been removed from Brown's Twitter page.

There are reports the two started throwing blows (and bottles!) over Chris' ex girlfriend, Rihanna, who Drake is rumored to have hooked up with.

A few hours before the brawl, TMZ shot footage of Drake leaving the London hotel ... surrounded by some diesel-sized hired muscle. No word if they were involved in the bar fight, but wow ...  that would be scary.
