Justin Timberlake showed he has deep pockets when he left a tip of £2,450 after visiting a nightclub.
The singer partied until 4.20am, The Sun reported, at the club in the German city of Cologne after being invited by the owner who said that drinks were on the house.
The Mirrors singer visited the club with a 25-strong entourage after his concert, the newspaper said.
Nina Blum, 28, who served drinks at the Crystal Cologne club, said of the tip: "We were all really amazed," while the owner called the star "a real gentleman".
Justin, who is performing on his The 20/20 Experience World Tour, is set to headline this year's V Festival.
