At this point in her career, Ariana Grande is somewhat familiar with bad press. Numerous (unsubstantiated) sources have branded her a diva, then there was that whole donut-licking incident and her flippant joke about how terrible America is. She's since apologized for those last two, but until she issues some sort of statement, her latest gaffe might lend some credence to those diva rumors.

According to a report from The Mirror, the “Focus” singer dropped out of a scheduled appearance on The Jonathan Ross Show at the very last minute, forcing Ross to improvise a new closing segment for the television program. He settled on having the other guests — Joan Collins, Danny DeVito and Sheridan Smith — fill in with a group karaoke performance of "Nine to Five."

He reportedly said, "Ariana is in town. We were told she would be in the car at 6pm to be here for 7pm then it got to 7pm and she was not in the car – 7.30pm and she is still not in the motherf—king car. So I don’t think we can hold out much hope.”

Ross continued, saying he wasn't even informed as to why Ariana canceled: “I don’t know what it is. We are going to give Ariana the benefit of the doubt and not say anything mean or judgmental. I apologize to anyone who might have come along hoping to see her. She was booked but the lazy little f---k has not come. Maybe she has gone to her first Nando’s."

Ariana has yet to address the cancelation.
