Guess Who (stylized as GUE?? WHO) is the fourth extended play by South Korean girl group Itzy. It was released by JYP Entertainment on April 30, 2021. The EP was released for pre-order on March 22,[2] and contains six tracks, including the lead single "In the Morning". The physical album comes in three versions: Day, Night, and Day&Night. The EP is primarily a rap-styled K-pop record that combines EDM, hip hop, dance, dance-pop, trap, Latin trap and bossa nova elements.
Guess Who was subject to generally mixed reviews from music critics, who complimented the record's cohesiveness; however, some found the material controlling the vitality of the group. The EP was commercially successful, marking Itzy's first and highest entry on the US Billboard 200, peaking at number 148, and peaking at number 2 on the Gaon Album Chart. In May 2021, Guess Who was certified Platinum by the Korea Music Content Association.
The lead single, "In the Morning", peaked at number 10 on the Gaon Digital Chart, becoming the group's fifth top-ten single, as well as the group's third single to enter the top five of the Billboard World Digital Song Sales chart. To promote the EP, the group performed on several South Korean music show programs, such as M Countdown and Inkigayo.
