Blame it on the alcohol.

Sam Smith had a lot to celebrate after taking home four Grammy awards on Sunday, but he's paying for it today.

"I am on another level of hungover right now," he posted along with the above pic on Instagram Monday afternoon. "Literally feel like I'm dying haha."

Smith also shared this gem captioned "me right now" along with several "loudly crying face" emojis.

Thank God for room service. "What actually happened last night?" he wrote. "I am monumentally hungover and keep spontaneously crying lol."

So what did actually happen after last night's awards ceremony? The "Stay With Me" singer, 22, threw one helluva bash at a private residence in Bel Air. No press or photogs were allowed inside, which is probably why the star-studded crowd felt like they could kick off their heels and really let their hair down.

Taylor Swift, Katy Perry, Ed Sheeran, Hozier, Haim, The Weeknd, Skrillex, Disclosure, Darren Criss, Diplo, Rita Ora, Johnny Wujek, and Paul Oakenfold were just a few of the people in attendance. The soiree was presented by Hangar 1 Vodka and Dobel Tequila so Smith's hangover certainly makes sense.

Swift, 25, arrived with Sheeran who did not bring along his Grammys performance partner, John Mayer, who also happens to be one of Taylor's exes. While that awkward situation was avoided, the "Shake It Off" singer was in close proximity to Katy Perry. Swift was all about peacemaking last night squashing beefs with Kanye West and Diplo, but Perry clearly wasn't on her "to make up with" list. Guess we can still count on Taylor to perform "Bad Blood" when she hits the road later this year.

In friendlier news, Swift did seem "cute and flirty" with "Take Me to Church" singer Hozier.

"They were talking for a lot of the night, laughing, and looked cuddly," said one partygoer. But don't read too much into that. Sources also say Taylor was the "life of the party" per usual, having a blast with many of her famous friends, including the Haim sisters and the party's host, Mr. Smith.

The shindig went until about 4 a.m., so we're sure Sam isn't the only one who feels like he's "dying" today.
