Justin Bieber enlists Kris Jenner's toyboy Corey Gamble to play bodyguard as he steps out for lunch in Beverly Hills

The Baby hit maker teamed a Metallica T-shirt with black jeans and shaded his eyes with blue mirrored sunglasses.

He displayed a slightly bouffant hairdo and was spotted taking a quick selfie to check himself out as he headed across the parking lot.

Corey was seen in a graphic-print T-shirt and black trousers and kept a professional demeanor throughout the outing. 

The Jenner matriarch's toyboy, 34, is employed by Bieber's manager Scooter Braun and normally acts as the pop star's road manager.
