When cardmembers use participating Citi credit cards through Dec. 28, they will be automatically entered for a chance to win one of two grand prizes: joining Nickelback on their next North American tour for a backstage experience in three cities or joining Blige in the studio during a recording session.

Complete details on the contest are available at Stories.Citicards.com.

Other artists who have participated in similar promotions include Jay-Z, Madonna and The Police.
