Recording artist, actress, model Solange Knowles entertains the guests during Roberto Cavalli Celebrates Fashion's Night Out at Roberto Cavalli Boutique.

Billboard's the Juice is invading your Beats by Dre headphones with the latest tracks, leaked or just realeased. Check out the Juice's playlist featuring Freddie Gibbs, Young Jeezy, Bruno Mars, Diggy Simmons, Omarion, YG and Solange.

I got to listen to Freddie Gibbs' track, "Stripes (Run D MC)," featuring Young Jeezy, last week and was instantly impressed at how well both musically meshed. Check out "Stripes (Run D MC)" on Gibbs upcoming mixtape "Cold Day in Hell."

Bruno Mars adds his magic touch to Diggy Simmons' love-struck track, "Click Clack Away." "Click Clack Away" is a leak, not an official release nor will it be used, Simmons tweeted. Diggy's first single, off his first studio album out in Sept., is set to debut this month. Both, single and album, are yet to be titled.

Omarion steps back into the scene with auto-tune, "Fall in Love." Featured guest, YG ("Toot It and Boot It"), adds a few dirty words to the first single from DJ Drama-hosted mixtape, "The Awakening" (May 11).

Solange debuted an unreleased oldie but goodie, "Left Side Drive." Solange writes over Boards of Canada's "Left Side Drive." "It's completely unofficial, and was just inspired by the song which I had a deep love affair with for years," Solange tweeted. "I am a huge Boards of Canada fan, and got the chance to work with them on Sol-Angel on "This Bird." Still feel honored to this day."
