Drizzy Drake says lies to his involvement with the Chris Brown altercation.

When bottles started popping and thrown across NYC club W.i.P. towards the hot buttered biscuit colored Chris Brown, recount of the night became muddled.
Behind posting the picture of an apparent laceration behind the tussle, Breezy tweeted the following:

 How u party wit a rich nigga that hate? Lol…. Throwing bottles like girls? #shameonya!

Niggas is p***y!

Bottles? It’s nothing! Lol http://instagr.am/p/L2Q1whPpUn/

And I’m the singer?

Niggas hiding in the bathroom b***h ass niggas!

Ok! Niggas stand behind security!!!! Ok! U don’t pay them enough!

Niggas throwing bottles! Y’all niggaz weak!

One could speculate that this was retaliation from Drake behind Brown's altercation with singer (and Drake's rumored jump-off) Rihanna back in 2009 and his explosive remix to Kanye West's 'Thereaflu' that disrespected the goat whisperer.
Drake has now responded via PR rep with the following:

Drake did not participate in any wrongdoing of any kind last night at W.i.P. He was on his way out of the club when the altercation began.”

[Drake] did not engage in any activity which resulted in injury to person or damage to property.

Once considered friendly, the pair has reportedly been at odds with each other for months. An eye-witness of the public pounding had this to say:
Shame on grown men acting like bruised runway queens!
