Alicia Keys couldn't stop belching after she ate just before going on stage.
The 'No One' singer - who was recently named the new face of Vitamin Water - admits she learned her lesson from the incident and now makes sure she eats a few hours before she is required to perform.
She said: "One time I ate right before going on stage and I had to hide my belches from the microphone - that was funny!"
Alicia decided to partner with the drinks company after finding she couldn't stop drinking the unique-tasting beverages, adding: "I don't partner with anybody, but this really was natural for me because I've been a fan from the beginning."
"I love their personality. Have you ever read the bottles? Don't you just feel naturally smarter when you read it?"
Jennifer Aniston and 50 Cent are among the celebrities who have previously lent their names to Vitamin Water.
