Adele is devastated she's had to give up eating pizza to protect her voice.
The 28-year-old soul superstar had been looking forward to indulging her love of the food while on tour.
However she has been unable to take in the country's famous pizzerias after being advised that eating the snack may harm her voice.
According to editors at Britain's Daily Star newspaper the singer told fans at a Los Angeles gig on Tuesday (09Aug16) of her disappointment at the pizza ban, saying, "I can't eat pizza anymore guys, how bad is that?"
Revealing the reasons for the pizza prohibition she added, "Because it's got cooked tomatoes on it which are bad for your throat and give you acid reflux. How bad is that, that I can't eat pizza, can you get over that?"
The Hello singer even compared her situation to a Shakespearean tragedy, as she said, "I'm in America and I can't eat pizza no more. It's worse than Romeo And Juliet! If only Shakespeare was alive, he could write about it!"
The star is on strict orders to protect her voice on tour, after having vocal chord surgery in 2011. Earlier this year (16) she revealed she had given up alcohol.
Adele's comments are not the first time she has addressed the subject of pizza on stage; at a concert in Chicago, Illinois last month (Jul16) she denied a report in Britain's The Sun newspaper that she had sent staff at a hotel in Oxfordshire, England on a 140 mil (225 kilometer) round trip to grab a meal from her favorite London pizzeria.
"First of all, I wouldn't make anyone do that," she said. "That's ridiculous, I would never order pizza and then eat it cold. I wouldn't do that. I might send someone out to get local pizza, but if I order pizza, I'm going to consume it."
