Justin Bieber was reduced to tears after laying eyes on his new custom Rolls Royce for the first time.

The What Do You Mean? hitmaker had been working with California's West Coast Customs founder Ryan Friedlinghaus to perfect the futuristic silver 2018 motor for the past three years, and when he finally saw the finished product, both men struggled to hold back the waterworks.

In video footage obtained by TMZ, Bieber is seen muttering through tears, "What?", and, "Oh my goodness", before Friedlinghaus replied: "You're gonna make me cry."

Explaining how the collaboration came about, Ryan said: "I get a phone call from Justin Bieber, he's like, 'Ryan, I just texted you this video of this car that's amazing.' We're always pushing that envelope of doing stuff that doesn't exist."
