Justin Bieber just gave a special treat to the ladies by slinging tequila and charming them with his piano playing and singing.
The 21-year-old singer recently rolled into The Nice Guy in L.A. and became the nicest guy himself as he landed on the piano to sing two of his own songs and also covered One Republic's 'Apologize,' reports TMZ.com.
Along with this, the 'What Do You Mean' hit-maker looked at a table of girls and dedicated a song to the birthday girl and even bought all of her friends tequila shots.
