NEW VIDEO: Chief Keef -- "They Know"

As the release date of Chief Keef's Interscope debut Finally Rich nears, the Chicago rapper shows off his new fancy lifestyle in the "They Know" video. "They Know" is not on the Finally Rich tracklist, and in the lip-synced video it's easy to see that Sosa has come a long way since the March release of his no frills "I Don't Like" video. For starters, he's traded in broken blinds and carpeting for a bigger spread with marble and hardwood floors. Lucky guy. Finally Rich drops Dec. 18.
