And while fans went crazy for it, Liam kind of wigged everyone out when he ended the performance.
His girlfriend and baby mama Cheryl was in the crowd supporting her man, but when Liam finished his song... he didn't exit the stage like a normal performer.
Instead, he went towards to audience and right up to Cheryl, grabbing her and leading her away as if they were exiting the arena together. It was so awkward even the host was bamboozled by it all.
Take a look:
Fans immediately took to Twitter to voice their confusion about the whole interaction.
Although it was pretty strange and definitely an awkward moment for live TV, some fans actually found it quite sweet.
Not sure whether or not Liam's intentions were romantic or not, but we can't help but cringe every time we re-watch it.
