RadarOnline.com wishes a happy 17th birthday to Nick Jonas, the youngest of the three Jonas brothers (and former flame of Miley Cyrus).

See more of the birthday boy!

Fun fact about the birthday boy: Nick's career in music started as a solo act but record producers were so impressed with brothers Kevin and Joe (who were backup singing for him) that they made them into a musical trio. Since then, the Jonas brothers have sold more than eight million albums, so we'd say they made the right move. How was he discovered?  In a barber shop when he was 6!

The young crooner also has a serious side. Having been diagnosed with Type 1 diabetes since at 13, he has been a vocal advocate for the cause. His Change for the Children Foundation works with five other groups to raise money and awareness.
