James Corden said he "really didn't want to mess it up" when it came to hosting Sunday's GRAMMYs, and despite his lift malfunctioning, tripping down the stairs and losing a shoe, so far he is absolutely nailing it.

Following Adele's flawless opening number, a blushing Corden had to crawl onstage and -- for a moment -- it did seem like the night was already going to pieces. But after tumbling all the way down the stairs as backup dancers began gyrating around him, it was clear it was all part of a gag.

"Stop! Stop it! This is a disaster," he shouted as a confetti gun exploded on him. "We have rehearsed this and rehearsed this and rehearsed this...We cannot allow this sort of mistake. This is the GRAMMYs, isn't it?"

It's probably no coincidence that the bit came immediately after Adele's performance, seeing as the last time the "Hello" songstress performed on the GRAMMYs' stage, there were so many glitches that it left her crying "pretty much all day."

After his pratfall, Corden opted for a less comedic opening monologue, instead embracing his musical side and delivering a Hamilton-style rap that touched on Beyoncé ("Slay the whole stage with twins in her tummy."), how Rihanna and Drake should date, and the unexpectedness of Lady Gaga's duet with Metallica. And no awards season monologue would be complete without a Donald Trump diss.

"Live it all up, 'cause this is the best," Corden rapped. "And with President Trump we don't know what comes next."
