Starz announced on Wednesday that its hit series, “Power,” will feature a special guest in this week’s episode, titled, “Happy Birthday.”

Just hours ahead of the announcement, 50 Cent took to Instagram to hint at the special appearance, saying, “Your not going to believe who we got on the show.”

Not too long after, the network revealed that Grammy and Pulitzer Prize winner Kendrick Lamar is set to guest star in the forthcoming episode, opposite 50 Cent.
