Lil Wayne fight after Floyd Mayweather victory [WATCH]: rapper confronts Marcos Maidana trainer after water bottle attack, 'let's go ni**a!' [VIDEO]

Following boxer Floyd Mayweather's Las Vegas victory over Marcos Maidana on Saturday night (May 3), total chaos ensued. At one point, rapper Lil Wayne was hit by a flying water bottle - and the Cash Money superstar was not happy about it.

Apparently, the "Mirror" emcee blamed the H2O attack on a member of Maidana's entourage (his trainer, to be exact). Backstage at MGM Grand, Weezy made a rather heated confrontation that was ultimately captured on video:

At one point, Wayne can be heard yelling, "Let's go, ni**a!" Thankfully, the altercation didn't turn violent.

Maidana's trainer was walking very closely behind Weezy when he was struck by the bottle. So, Wayne immediately reacted with some harsh words and threats. But before things got too nasty, both sides were separated. As TMZ reports, no further incident occurred.
