Wiz Khalifa is a Total Sweetheart in 'Roll Up'

Video from the rapper's new album 'Rolling Papers' features a guest appearance from Cassie

Wiz Khalifa's new single "Roll Up" may be the nicest rap hit in years, with the Pittsburgh rapper declaring his unconditional support to a girlfriend in the track's gentle yet immensely catchy chorus. The video is equally sweet, with the rapper wooing a girl played by R&B singer Cassie on a Venice Beach basketball court.
