It's official: It is Adele's world, and we are all just living in it.

Nielsen Music reported that the "Hello" singer now holds the title for most U.S. albums sold in a single week. Her third album, 25, racked up 2.43 million albums sold in three days -- yes, just THREE DAYS!

Adele said "Bye Bye Bye" (see what I did there?) to the previous record holder, 'NSYNC, whose album No Strings Attached held the crown for over 15 years with 2.41 million albums sold in a week.

But get this: Adele's not even done. She has more than three days left in the sales-tracking week, which means that 25 will just get bigger and bigger and bigger with industry forecasters suggesting the album could finish with 2.9 million sold.

These numbers are simply staggering considering that since Nielsen Music began tracking sale purchases in 1991, only Adele and the boy band have sold over 2 million in their respective albums' first seven days of release.

But they aren't the only ones to surpass a million in the first week. There are only 20 albums, including 25, to have achieved that goal. So who is a part of the million album club? Here's a look back at all the artists.
