The newly single 20-year-old singer shared a photo collage on his Instagram account of him and Lagerfeld, reported People magazine.
"Big things coming with my friend Karl Lagerfeld," Bieber captioned the picture.
The singer is bare-bodied in the photos.
In the two other images, the 'Baby' singer can be seen sitting next to the 81-year-old silver haired designer who wore his classic black suit and shades.
Whether Lagerfeld is styling or shooting the star is not known.
