Naturally, he smashed it.
However it wasn't just his incredible performance that had fans talking.
Instead, it was the fact that Louis was appearing on the show the exact same night that his enemy Naughty Boy was.
Back in the One Direction prime days, Louis and Zayn Malik had a pretty public fight with him. Now, fans were highly anxious to find out that the two would be in the same room together.
Neither Louis or Naughty Boy have made any comments about each other from the night, so it's safe to say that they're probably over it, or didn't even cross paths on the night.
