We've all been there - waking up after a heavy night with a half-eaten burger stuck to our face, wondering how on earth we managed get home and crawl into bed.
But after it happened to Rihanna - who was recently hospitalised for exhaustion and dehydration - on a night out in London on Saturday, she claimed it was her "last hurrah".
She tweeted: "You will be very disappointed to know last night was my final hurrah til my vacation! I ain't about this life."
So of course, last night she decided to stay in on the sofa in her jimjams watching Antiques Roadshow.
Or not.
Despite swearing off her hardcore ways, RiRi was spotted sneaking out of Boujis nightclub in Kensington at 3.15am after a night of partying with the likes of Chelsea ace Didier Drogba.
However, she did manage to stay off the sauce despite staying out until the wee small hours, tweeting: "Interesting night! Sober and tired and bored." Sure that's not a smear on your company, Didier.
On Saturday, she spent the night boozing at Dstrkt following her pals' Kanye West and Jay-Z's gig at The O2, and woke up feeling a little worse for wear, prompting her to call time on her partying.
She tweeted: "U know life is great when u wake up at 9 am DRUNK!!!!!
"You know it was a good night when u wake up n run to your BFF's room like... How did I get in my bed? Did I walk? Stumble? Get carried?"
And after realising she'd missed a flight to Madrid where she was meant to work on a shoot, she roped in Jay-Z to help her get the day off to nurse her sore head.
"So ummm.... I'm supposed to be on a plane rt now!... JayZ saved me!!!!! I got an extra day off sorry @HiHatprod"
We wish we had pals like Jay-Z to help us blag a day off work when we're hungover.
