Bieber's debut album, My World 2. 0 (2010), debuted atop the Billboard 200, making him the youngest solo male act to top the chart in 47 years. The album also contained the internationally successful single "Baby", which became the highest certificated single of all time in the US. His second album, Under the Mistletoe (2011), was the first Christmas album by a male artist to debut at number one on the Billboard 200, while his third album, Believe (2012), saw experimentation with dance-pop and mature themes. Following Believe, Bieber's public image went through a drastic change through various controversies and legal issues during 2013 and 2014, leading to Rolling Stone dubbing him "Bad Boy" on their March 2014 issue. However, starting in 2016, he has been setting his priorities on repairing his public image, by taking responsibility for his past wrongdoings and focusing on his mental health. In February 2016, GQ released an article about Bieber's commitment to "reintroduce" himself.
