Louis played his debut match at Doncaster Rovers on Wednesday night (26 February), in front of thousands of loyal fans.
Dressed in the red and white kit, the 'Best Song Ever' star got (as you'd expect) a mammoth cheer when he arrived on the pitch in the 65th minute.
According to the club, a reserve match usually sells around 100 tickets, but last night 5,000 were sold as 1D fans travelled from across the world to support their man in action.
BBC found ticket holders from as far away as the US, Italy, France and Denmark, who'd all travelled to England purely to watch Louis play.
Proceeds from the match against Rotherham United, which ended 0-0, went to the Bluebell Wood Children's Hospice.
Louis, 22, was clearly rather overwhelmed by the whole experience, tweeting afterwards: "Wow what an incredible experience. Can't put into words how I feel :) I will never forget pulling on my own Doncaster Rovers shirt !!
"Really can't thank the team, the gaffer and every single person involved at Doncaster Rovers enough! I feel like a 10 year old again! And obviously a huge, huge thank you to everyone who came down :) a real credit to our fans :) hope it was a good day out!"
Louis' girlfriend Eleanor was snapped in the stands, while his grandfather Keith Tomlinson was also there, looking proud as punch.
"Just been down to the ground. It's buzzing with excitement. 1D fans prove again they're the best in the world. Great job by the stewards too," he said.
Louis' One Direction bandmates weren't there (perhaps because can you imagine the pandemonium that would cause?!), but Niall Horan did send his support, tweeting: "Goodluck Tommo mate!! @Louis_Tomlinson!"
Louis signed for Doncaster Rovers as a non-contract player last year His debut match had been set for September 2013 but he was forced to withdraw after injuring his leg at a charity match in Glasgow.
