Justin Bieber got his start a few years back by singing covers of hit songs and posting them on YouTube. Now that the Biebs is one of the biggest stars on the planet, it seems he still enjoys singing Usher songs — though he definitely isn't the one uploading them to YouTube these days.

Check out the Biebs' freshest covers, including Usher's "Climax" and Carly Rae Jepsen's "Call Me Maybe."

The Biebs Sings "Climax"Bieber paid a visit to the KIIS FM studios earlier this week for a segment with Jojo on the Radio. During the interview, the 18-year-old star showed off his range with a few bars of Usher's latest single.




The Biebs Sings "Call Me Maybe"
Carly Rae Jepsen probably wouldn't have a huge hit if it weren't for Bieber, who tirelessly promoted the fellow Canadian on his personal Twitter page and helped sign her to his label. He sang a few verses of the summer song when he dropped in at FUSE Studios earlier this week.



The Biebs Sings "Let it Be"
It takes some guts to cover an iconic band like the Beatles on New Year's Eve live in front of thousands and thousands of people, not to mention the millions watching from their family rooms on TV. But, Bieber was up for the task. He helped ring in 2012 in Times Square with his smooth rendition of the hit, which also featured some sweet guitar playing courtesy of Carlos Santana.



The Biebs Sings "3AM"
Bieber was only 4 years old when Matchbox 20 debuted their hit "3am" in 1998, but the Biebs performed the tune at the Georgia Music Hall of Fame induction ceremony in 2011. He finished up the performance with a bit of Usher's "You Got it Bad."
