Chris Brown, Aaliyah Serenade School Kids In Video-Shoot Snippet

CB echoes Jon B and twists late singer's vocals in 'They Don't Know.'

Chris Brown wanted to share a special moment with his fans when he shot the video for "They Don't Know," his upcoming track which will also feature Aaliyah, so he decided to go to South Los Angeles to spread the love.

Over the weekend, local Cali rapper Uiie Popcorn posted a behind-the-scenes clip to YouTube that caught Chris Brown filming scenes from "They Don't Know" sitting in front of a school surrounded by a crowd of children. "And for those of y'all who don't know this is a song with me and Aaliyah, that nobody ever heard before," Brown tells the children.

The majority of the eight-minute clip is backed with Uiie's own music, but there are scenes where fans get a sonic snapshot of Brown's new track. The song, which features previously unheard Aaliyah vocals, has a distinct old-school feel to it. "Don't listen to what people say," Breezy sings, drawing inspiration from Jon B's 1997 single "They Don't Know."

In between every line that Chris delivers Aaliyah sings "how could they know," accentuating his vocals.

The track is slated to appear on Brown's upcoming album X. "I shot it in the hood, I went to the 60s. I went to Cedar block," Brown said on Tuesday at a L.A. press conference for the 2013 BET Awards. "It's both worlds, it's bringing both words together in the video trying to uplift the poverty side of the community and just showing them where I'm from."
