Nelly Makes it Rain in Dallas Strip Club ... Shake Ya Tailfeather! (VIDEO)

Nelly just proved he's still got money to burn by unloading a massive stack of cash on some Dallas strippers.

The rap star hit up VLive Dallas with a few friends Monday night and we're told the rain produced 31,000 singles.

The club can thank Drake for Nelly's donation -- we're told he showed up after hearing Drake rap about the joint.

So, we're guessing Drake will be sending over an invoice any day.
