Tim McGraw jokes he's 'hydrating' after collapsing on stage earlier this month

The country singer collapsed from dehydration during a performance in Dublin.

The 50-year-old musician posted an underwater photo of himself deep-sea fishing. He captioned it, "Hydrating!"

A rep for the singer later said in a statement that McGraw was suffering from dehydration.

McGraw himself blamed the incident on "lots of flying and dehydration, and said that he might need to ease up on his exercise regimen.

"I gotta cut short my workout,” McGraw told The Blast, after arriving at JFK Airport in New York City the day after he collapsed.

Now, it appears the singer took his own advice, taking what looks to be an island vacation with his wife of 20 years.

He posted a shot of her beneath a beach towel and captioned it, "We love our mummy!!!"

McGraw and Hill will resume their Soul2Soul world tour in Richmond, Virginia, on May 31.
