Justin Bieber has a new sports car, thanks to his rap mogul pal Bryan 'birdman' Williams.

The Baby hitmaker showed off his new ride in a post on Instagram.com on Monday (07Apr14), sitting behind the wheel of the shiny red Bugatti, which is one of the fastest and most expensive cars in the world.

He added the caption, "Uncle Stunna (Birdman) luv. My first Bugatti #generosity."

Birdman's extravagant gift reportedly cost an estimated $2 million (£1.2 million).

While Bieber has been in the studio working with the Cash Money Records co-founder, he also treated Birdman's daughter Bria Williams to a serenade during her Sweet 16 birthday party last month (01Mar14). Bieber recorded a special video message, which was played during the party.
