McGraw was in Ireland as part of a three-day, three-city country music festival called Country to Country.
McGraw kissed Hill's hand as they walked out on stage for the first performance of their Soul2Soul tour outside the United States and later introduced her to the crowd as "my wife, Mrs McGraw". Hill was seen wearing a black turtleneck and jeans along with a black raincoat as she was shielded from the rainy weather by an umbrella. "And I apologize, but I made the decision that he can not come back out on stage".
Meanwhile, a rep for the singer said that he had been attended to on-site by local medics and is expected to be "fine'".
McGraw reportedly had just finished a song when he sat down, then "slumped to his knees as he walked off stage". Readers can press play above to watch the country star and her band address the crowd, the members of which responded classily.
"But look, it's been really good to me".
A representative for McGraw said that the artist "will be fine". The crowd cheered in support and began chanting "Get Well Tim".
