Now at this time in her career, Gaga is giving all media
the silent treatment; she told Oprah Winfrey on 'Oprah's Next Chapter' in March that "Other than this interview, Oprah, I do not intend to speak to anyone for a very long time. No press, no television."
So how do we know that she vomited offstage? She told the crowd in Bucharest what had happened. “I went backstage and vomited, and I did not want you to see this," she said when she'd returned. "It happens to me sometimes.”
Lady Gaga: Illness on the road
As she intimated to her audience, it is not the first time she's had health issues in the midst of a performance. She's suffered from exhaustion on the road and while performing in London last year she vomited during a show; that was said to be due to food poisoning.
Gaga is in the midst of her 'Born This Way Ball' tour
and will remain doing dates in Europe until early in October. In late October she will play in Mexico City and then she moves on to Central and South America.
