Zayn shaved his head COMPLETELY BALD!

The singer showed off his new look in an Instagram post by his mom Trisha. The former One-D'er went the totally shiny route -- leaving not even a millimeter of hair on his head. He's posing with girlfriend Gigi Hadid, who has a huge smile on her face (does she really like it?!) and his mom, who's kissing her son's slick dome.

He's shaved his head before, but never completely -- and while his beautiful eyes and long lashes have always been his best feature, we prefer our Zayn with a bit of hair!

Meanwhile, Z is set to release the first single off his new album -- "Dusk Till Dawn" featuring Sia. Malik posted a teaser for the music video and the single art. The video will star Girls alum Jemima Kirke and is directed by Mark Webb. Check it out!
