Video footage from some very lucky commuters shows Harry giving an impromptu performance, prancing around to his absolute banger "Kiwi" and "Lights Up" while literally flying around on a zip-line harness, and grinding on a car.
There was even a large group of people dressed in watermelon outfits, no doubt to celebrate his second single "Watermelon Sugar," from his upcoming album to be released December 13.
What we would DO to be this Honda:
It was revealed that the stunt was for his appearance on an upcoming episode of The Late Late Show with James Corden, who did a similar thing with the cast of Aladdin when the movie was released.
But Harry's buns aren't the only thing making headlines this week. After his recent Saturday Night Live show, Harry has copped some backlash for a joke he made about former One Direction bandmate Zayn Malik.
"I'm not in a boy band anymore. I'm in a man band now. I was in a band called One Direction," Harry said in his monologue on the show.
"I love those guys. Niall, Liam, Louis..." the "Watermelon Sugar" singer then pointedly struggled to try to remember the fourth band member's name (Zayn), before concluding "and, uh, Ringo! Yeah, that's it."
A lot of w fans had a huge issue with Harry's jab, calling it insensitive or immature.
"Joke or not, imagine the twitter outrage if Zayn went on international TV and threw shade at Harry!" exclaimed another fan. "Zayn hasn't said a word about them yet with the exception of Niall they all can't seem to stop with the pettyness!" they continued.
However, as beloved as Harry is by his fans, they were right there by his side defending him.
One fan wrote: "The joke was that Ringo was the first to pursue a solo career in The Beatles just like Zayn was the first in One Direction, like I don't know why everyone thinks it's so deep."
Another said: "We all know Harry didn't have ill intention, we all know SNL wrote the joke, we all know Harry loves Zayn. We all know it's gonna blow over in 2 days. It's getting really sad".
