One Direction
The As It Was singer sent fans wild with speculation thanks to a hastily-deleted photo he posted on Instagram.
"God bless you, brother."
The former One Direction singer's interview with Logan Paul was met with a backlash from many fans.
Since One Direction went their separate ways, all five members of the band have launched solo careers, with varying levels of success.
The pair were famously close friends during their One Direction days, but fell out after Zayn quit the band.
The singer recently made a string of claims about past tensions within One Direction.
The singer also said he and another member of the group "hated each other" while they were in the band.
"Giving Liam at the Oscars a run for his money," one person tweeted.
Six years after they parted ways, the As It Was singer has insisted he still feels "deep love" for the other 1D boys.
After Lizzo noted that her fans were called the “Lizzbians,” the One Direction singer joked that he called his followers the “Horandogs.”
