Justin Bieber has reportedly taken the decision to give up alcohol for celebrity chef Jamie Oliver's cookbooks and his girlfriend Selena Gomez.
The 'Boyfriend singer's friends have revealed that he knows alcohol isn't good for him and wants to get rid of his habit, while ditching his "bad influence" pals in favour of quiet nights in with his on-off girlfriend , the Mirror reported.
According to sources, the 20-year-old popstar has moved on to the next chapter of his life and wants to put all the "bratty child and bad boy" stuff behind him, which is why he took the decision a few weeks ago to grow up.
Insiders added that Bieber he sees one of his old gang, Lil Twist, but only in his home and has found a true hobby in cooking and has built up a collection of recipe books.
