Hey sweetpea,
yes, he did! (and sorry, Tumblr ate my original reply, so I had to take a screenshot of your question)
❗️EDIT 20 April 2026: thank you Miglena @quitegenerous for informing me about an even earlier instance of Louis with a flag on stage 💖
So far, Louis has walked around the stage draped in 3 different flags, but has raised 4 flags in total. (and if I missed a flag, please let me know and I will add it here!)
The first time he picked up a flag on stage was on 13 November 2019 at the Premios Telehit festival in México. What's even more interesting, though, is that before that, there was a big rainbow flag 🏳️🌈 right in front of him and the lore I found is that his gesture meant he was asking for the rainbow flag, but that the fans didn't understand that (apparently he 'asked' twice!), so they didn't throw it to him.
[i gotta say if I were that fan, I TOO would not have understood that gesture as "give me that flag" and i'm honestly a little doubtful that's how he really meant it, but also i'm not in his head, so maybe he was super shy about asking and did mean it like that and hoped they would understand him? 😭 My heart. Sadly, we will probably never know 😭]
It gets more interesting from here on out. A while later, during Kill My Mind, in this video you see that he walked the catwalk and a rainbow flag 🏳️🌈 AND the Mexican flag 🇲🇽 had already been thrown on there:
and a bit later, he walked the catwalk again while saying his goodbyes (video here) and he chose to pick up the very Mexican flag from the earlier video instead of the rainbow flag 🥹 (that must've been such a tough choice 💔) and then he waved the Mexican flag for 3 seconds, then threw it + his hat into the direction of the fans with the pride flag:
ALSO, as the 🍒 on top, he was wearing an Umbro shirt at that show:
Then, 4.5 years later, he did it with the Mexican flag (that had a lot of fan signatures on it) on 4 June 2024 in Queretaro, México:
Then he did it on 10 August 2024 at Sziget Festival in Hungary. He asked for and got a Doncaster Rovers flag from a fan and draped it around himself on stage:
And on this current tour, in Madrid, Spain on 13 April 2026, he draped himself in the Spanish flag:
I also want to share this beautiful concert report of a fan bringing a Louis custom rainbow flag 🏳️🌈 to a show on 14 June 2022 in Mexico City, México and Louis' reaction when he noticed her rainbow flag.
and Shay @hl-obsessed made a beautiful manip of something we'll hopefully see for real in the future one day, I fully believe it:
...until then, we'll continue to bring them for him 🥹🏳️🌈
