Justin Bieber is all about the serenade these days.
As previously depicted, the singer belted out a seductive version of "I'll Make Love to You" a few days ago.
He then followed that appearance by making the life of a Make-A-Wish Foundation fan by singing One Less Lonely Girl to her.
Last night, meanwhile, TMZ cameras captured Bieber walking out of The Grove in Hollywood when he came across a couple who had just gotten engaged.
He started to sing that same Boyz II Men song to them, only to then ask the man to finish it off... before ordering the pair to "make out."
Pretty cute stuff. Pretty funny stuff. Watch now.
