Source: John Medina/Prince Williams Chris Brown has been putting on a show for his loyal Team Breezy fanbase, and now he's given Summer Walker the "Take You Down" onstage treatment. Chris has spent the summer plucking women from the crowd to serenade during the part of the show where he treats someone to a grinding session for the audience to see, but recently he's taken it up a notch. Following his LA stop where he and Kayla Nicole put the girls in a frenzy, Brown decided to tap his sometime opening act artist, Summer Walker, for a special moment in Las Vegas.
