Country music star Tim McGraw on Sunday night collapsed onstage while performing his hit “Humble & Kind” in Dublin, Ireland.

McGraw's rep told Fox News the singer was attended on site by local medical staff and he "will be fine."

"Tim McGraw was suffering from dehydration in Dublin this evening at the C2C show," a rep for McGraw told us. "He and Faith thank everyone for their love and support and look forward to seeing their Irish fans again soon."

Rolling Stone was first to report the news that the crooner left the crowd shocked when he dropped to his knees and sat down.

McGraw's wife, singer Faith Hill, can be seen in a video on a fan's Instagram page addressing the crowd at the show, "He's been super dehydrated. I apologize, but I made the decision that he cannot come back out on stage."

McGraw, who was performing as part of the Country to Country festival in the U.K., had performed Friday night in London and Saturday night in Glasgow as part of C2C, a three-day, three-city country music festival.

The duo is scheduled to begin their 29-city Soul2Soul tour in the U.S. on May 31 in Richmond, Virginia.

McGraw and Hill have been married for 21 years. Their first duet together, "It's Your Love," was on McGraw's 1997 "Everywhere" album, which was followed by "Just to Hear You Say That You Love Me," from Hill's multiplatinum album "Faith."

Since then, they have had several popular duets, including their latest, "Speak to A Girl," which jumped into the Top 10 of Billboard's Hot country songs chart after they performed it on the ACM Awards.
