Justin Timberlake left 4000 $ Tip in Germany

Just Timberlake is more than generous!

He recently joined a group of 25 people for a night out at the Crystal Cologne club in Cologne, Germany where he performed a pair of concerts for The 20/20 Experience World Tour, on Sunday and Tuesday.

Although the singer was invited to get free drinks there, he left a tip over 4.000 $ for a group of waitresses who served him!

Justin apparently had a great time there, since he stayed until 4:30 a.m. and shocked staff with his generosity.

“We were all really amazed”, said one of the waitresses.

Last year, Justin and his wife Jessica Biel put their baby plans on hold while Justin concentrated on resurrecting his music career.

“Any baby plans Jessica may have had have been put on hold because Justin just wants to work right now”, a source said.

"They’ve had a long, hard talk about it, and Justin convinced Jessica that they can wait a little, especially since he will be promoting his music all around the world this year. He’s told her he wants to be a hands-on father, and that won’t be possible with everything he’s got on at the moment".

"Jessica is actually in agreement with Justin, she wants him with her every step of the way, so she’s reluctantly agreed now’s not the time to have a baby".

“She’ll just have to play second fiddle to his music for the time being”.
