Last week, country star Tim McGraw made headlines after he collapsed during his set at the Country2Country festival taking place at Dublin's 3Arena across the weekend.

His wife Faith Hill later took to the stage to explain that "He's been super dehydrated", before apologising and confirming that he would not be returning to the stage.

Less than a week later, it appears that McGraw is feeling a whole lot better, judging by the picture posted to his Twitter account over the weekend.

That's certainly one way to 'hydrate'...
