Bandmates for life.
Harry Styles supported his fellow One Direction alum, Niall Horan, at Horan’s concert at Co-op Live in Manchester, England, on Tuesday.
Styles, 30, was seen singing and dancing in the crowd as Horan, 30, performed the One Direction song “Stockholm Syndrome” in a fan video shared on X (formerly Twitter).
The “Watermelon Sugar” singer wore a yellow cardigan sweater over a white T-shirt to the concert.
Fans of One Direction — which broke up in 2015 — went wild seeing the video of Styles at Horan’s show.
“WOW,” one person tweeted.
“Love this ‘H’ having a great time showing support for Niall,” another fan wrote.
“Reunion when?” a different fan asked.
Horan is currently on his The Show: Live on Tour, which kicked off in Ireland in February. His final show is scheduled for October 9 in Colombia.
The “Meltdown” singer launched his solo career after One Direction went on an indefinite hiatus following Zayn Malik’s exit from the group.
The former boy band — made up of Horan, Styles, Malik, 31, Liam Payne, 31, and Louis Tomlinson, 32 — formed under the leadership of Simon Cowell on the UK version of “The X-Factor” in 2010.
All five members were teenagers when the group came together.
One Direction became one of the best-selling boy bands of all time before they disbanded.
Since the breakup, Horan has released three studio albums — 2017’s “Flicker,” 2020’s “Heartbreak Weather” and 2023’s “The Show.”
But it’s Styles who has had the most successful solo career of all five 1D alums, by far.
He came out with his second solo album, “Harry’s House,” in 2022 and then went on his Love On Tour, which lasted over 22 months until July 2023.
The “As It Was” singer also starred in the films “Don’t Worry Darling” and “My Policeman.”
Despite moving on from One Direction, Styles still showed love to the band that made him famous at the 2023 BRIT Awards.
While accepting the award for British artist of the year, Styles said in his acceptance speech, “I want to thank Niall, Louis, Liam and Zayn because I wouldn’t be here without you either. Thank you so much.”
Two months later, Styles hinted at a One Direction reunion on James Corden’s final “The Late Late Show.”
“I think I would never say never to that,” he said.
