Remember during the summer when rumors began swirling that Chicago Bulls stars Derrick Rose and Jimmy Butler were having difficulty getting along in the same backcourt? We may have found the reason why.

Video has surfaced today of Butler getting all the way turnt up before practice to...wait for it...Florida Georgia Line. You know, that Top 40, bubblelicious, country-pop song called "Cruise" that girls in cowboy boots and jean shorts were belting all summer long. Butler is going all the way in here, dancing around what looks like the Bulls practice gym and singing every word. Even stranger? He's wearing a TOPSZN shirt while doing so. Drake would be ashamed!

This obviously isn't the culprit behind Rose and Butler's rumored rift, if there even is one, but it doesn't make this video any less hilarious.
