Joel and Benji Madden host several guest rappers, including Wiz Khalifa, Casey Veggies and Machine Gun Kelly, on their new Madden Brothers mixtape. This clip from the Good Charlotte brothers features Kelly, who inspired the Maddens with his over-the-top energy, says Benji. "The day we met MGK, Joel and I both walked away saying, 'He reminds us of us at his age'... MGK makes any track exciting, and in front of the camera he commands everyone's attention." The song, the video and the whole mixtape were made "for no other reason" than to be creative and to have fun, says Madden: "Mission accomplished."
