Justin Bieber has once again made like a glorified street performed.
About a week after he stunned those at a hotel with a rendition of "I'll Make Love to You," and then also serenaded a newly-engaged couple outside a restaurant, Bieber showed up at The Nice Guy in West Hollywood around 9 p.m. on Monday night.
He was joined there by Cody Simpson, as the two treated the dinner crowd to their 2014 duet, "Home to Mama," along with the Edwin McCain track "I'll Be" and Tracy Chapman's classic "Fast Car."
Bieber then left after about 30 minutes, though Simpson lingered for a while longer
