ITZY dropped a new teaser poster for their official 2021 comeback. Weeks after treating their fans with a virtual engagement, alongside a fan-dedicated track, the five-member group now persists in building the hype over their upcoming mini-album, Guess Who.

AllKpop said that the K-Pop idols "exuded their girl-crush charms" in the latest poster. It features the members in a "high-contrast black and white" theme as they pose with "radiating" charisma.

The "IT'z Summer" singers released the material on Wednesday. This comes days after they unveiled the official tracklist of the album.

Earlier this week, the fans and followers have obtained the titles of the tracks that Guess Who houses. It has six songs, including the title track, "(M.A.F.I.A.) In The Morning," which J.Y. Park composed and arranged for the group. The other five titles are "Sorry Not Sorry," "KIDDING ME," "SHOOT!", "Wild Wild West," and "Tennis (0:0)."

The mini-album will officially arrive on April 30 at 1 PM, KST. It will, also, serve as the group's return to the scene since the release of Not Shy last August.

ITZY first announced the arrival of their mini-album earlier in March. It took place a day after they had their first Fan Party Live event in celebration of their second anniversary. The official statement, also, came after the group released their special song for the fans, carrying the name of their fandom, MIDZY.

They have since dropped several teaser materials on various social media channels. The public now seemingly expects to witness more in the next few weeks as the release date approaches.

Aside from gearing up for their upcoming track collection, the members of ITZY are, also, preparing for their newest partnership with global cosmetic brand Maybelline. Earlier this month, the label announced that the five K-Pop idols will join the likes of Gigi Hadid and Storm Reid as "global spokesmodel."

Dazed magazine noted that the group made history, considering that they are the first K-Pop idols to represent the famous brand. In addition to this, they are, also, the first musical act to do so.

The publication continued that the partnership will launch this spring. There will be several campaigns for various product lines, including Maybelline's Hyper Easy Liquid Eyeliner, SuperStay Foundation, and Ultimate Lipstick series.

The label's New York global brand president, Trisha Ayyagari said in the press release that she has been "watching ITZY's inspiring rise," adding that she was "drawn to how dynamic they are both as a group and individuals." She emphasized, as well, the five K-Pop idols "champion self-love, individuality, and self-expression to their fans and global community."
