Zara and Mike Tindall were seen belting out the tunes at King Charles' Coronation concert - but his late night antics appear to have caught up with him.
The popular royal couple have had a few late night parties in recent days, having returned home at 2am after having dinner with other members of the Royal Family on the night before the ceremony.
It didn't impact them during the Coronation, but it seems the weekend's busy schedule has finally gotten to Mike.
