Justin Bieber wants to be a dad by 30

Justin Bieber wants to settle down and have children before he turns 30.

The 22-year-old star revealed it would be his "biggest dream" to have a family in an interview in the April issue of Glamour magazine (16).

When asked if he wants children the star was adamant, "Yes! I'd love to be settled down by the age of 30".

The Sorry singer also revealed a more mature side in the quickfire Q and A session, admitting that if he could change one thing about himself it would be to be "more patient".

In terms of what he looks for in a partner, the star revealed, "A genuine heart and great sense of humour," but refused to "kiss and tell" about the last girl he was intimate with, though he is rumoured to be dating model Hailey Baldwin.

It's a far cry from the controversy the Canadian faced over a year ago. The star had several run-ins with the law when he was accused of reckless driving in 2012 and was arrested in Miami with the singer Khalil in 2014, for driving under the influence with an out of date licence.

The pop singer has been working to improve his public image ever since.

Opening up about his latest album he said: "I don't view this (album) as a comeback, I'm just growing up."

It's a full turn around for the star who described himself as "Creative. Adventurous" and "loving".

In December (15), he showed a charitable side, by tweeting his support for The Lewisham and Greenwich NHS Choir's song A Bridge Over You which eventually topped the chart ahead of Bieber's Love Yourself to claim the Christmas number one spot.

Writing on Twitter he said, "I'm hearing this UK Christmas race is close...but the @Choir_NHS single is for charity... So... for 1 week it's ok not to be #1. Let's do the right thing & help them win. It's Christmas. @Choir_NHS good luck".
