Justin Bieber's second album Believe, is predicted to have the biggest debut sales week of the year, with predicted sales figures of as many as 440,000 albums.
The current best debut week of 2012 is held by Madonna's MDNA with 359,000: much lower than the 'Boyfriend' singer's predicted sales.
MDNA also holds a slightly less impressive title - it had the biggest drop in second week sales in history...
So far Believe has been getting good reviews from fans and critics, who have praised it for its mature sound and catchy singles.
Some have even compared 'Boyfriend' to the work of another famous Justin: Mr SexyBack himself, Justin Timberlake.
Over in here in the UK, Bieber is also expected to be No. 1, edging out Cheryl Cole's A Million Lights.
But with only 3,000 copies separating them as of yesterday, it's a far closer race here than it is in the US.
If we were Bieber, we'd be grinning too!
