New single, new style — Zayn Malik has gone green-haired...again.

The "Pillowtalk" singer, who released "Still Got Time" with PARTYNEXTDOOR earlier this month, debuted a brand new hairstyle today (March 28) on Twitter, and it's a bit of a throwback. Without so much as a caption, Zayn shared an image of his emerald locks spilling out over his face toward his camera's lens, and fans seemed mostly on board with the (kind of) new look.

"You look good with all the colors! how is this possible? Your parents did very well." one fan wrote in response, while another noted "I wish I had my hair like this."

Zayn previously dyed his hair green in June 2015, though it was much shorter and a little bit more fluorescent. Back then, fans most closely associated his new look with watermelon rinds, Shrek and a variation on a traditional highlighter.

Meanwhile, Zayn's gearing up for the release of his second album, which is due out this summer. "Just stop lookin’ for love / Girl, you know you still got time," he croons on the LP's first single, a breezy tune that's just right for the year's warmer months.
