Justin Bieber's comeback is complete after becoming the youngest male artist in US history to debut at number one on the Billboard Hot 100 chart.
What Do You Mean? has rocketed to number one - a spot higher than Bieber's biggest US hit to date, Boyfriend, which reached number two in 2012.
The grateful 21 year old, who teared up at the end of an emotional performance of the song at the MTV Video Music Awards last month, posted a video on Instagram thanking fans for his first Hot 100 number one.
He declared, "Looks like we did it! Finally... You guys are the best."
