The 24-year-old singer's mom, Tricia Malik, shared a picture Sunday on Instagram of Malik showing off his freshly-shaved head.
The snapshot shows Malik posing as Tricia kisses his head and Hadid smiles for the camera. Malik and his mom also spent time with Hadid and her mom, Yolanda Hadid, while celebrating the Islamic holiday of Eid al-Adha last week.
"Eid Mubarak to everyone... #BlessedDay," Tricia captioned a group photo Friday with Malik, Hadid and Yolanda.
Fans reacted to Malik's new look on social media, with many embracing the singer's dramatic change.
"Zayn looks beautiful no matter his choice of hairstyle, or the lack of it. I just want him to release music, and for him to be happy," one person tweeted Sunday.
"Just had to add @zaynmalik's freshly shaven head to the list of things that are brighter then my future #ZAYN," another person jokingly added Monday.
Malik is gearing up to release the new single "Dusk Till Dawn" featuring Sia from his forthcoming second solo album. He released the album Mind of Mine in March 2016 following his departure from One Direction.
