Carly Rae Jepsen's single 'Call Me Maybe' has been announced as the new US Billbaord Hot 100 number one.
The female star's song dethroned Gotye's 'Somebody That I Used To Know' with Maroon 5's latest release 'Payphone' making up the new top three.
Justin Bieber was quick to congratulate his protégée on her chart triumph admitting he was really proud of her success.
Taking to Twitter, he wrote: "Big Shoutout to @carlyraejepsen for getting her first #1 on BILLBOARD HOT 100!! SO PROUD!! CANADA STAND UP!!!"
One Direction achieved their highest single chart position for 'What Makes You Beautiful' after it climbed one space to number five.
Justin's 'Boyfriend' was also inside the top ten with Katy Perry and Rihanna also featuring in the latest rundown.
The chart success comes shortly after she surprised the audience at Capital FM's Summetime Ball 2012 when she was brought on stage to sing the track during Justin's set at Wembley Stadium.
This week's album chart saw Adele climb back to the top of the Billboard 200 with '21' scoring its 24th non-consecutive week at number one.
