Super songstress Adele is on route to sell a million copies of her latest album “25” by Christmas Eve in the U.S. for its third non-consecutive week, breaking yet another music industry benchmark.

The historic milestone would be added to the album’s already stellar record – after “25” became the only album to ever sell more than one million copies in multiple weeks, selling 3.38 million copies in week one and 1.11 million copies within week two of its release.

Overall, that would make “25” the biggest-selling album released in the US since Adele’s last album, “21”, which sold 11.37 million copies, after it was released in 2011.

The sales total for "25" for the week ending December 24 is scheduled to be announced on Sunday, December 27, 2015 – after Nielsen Music has completed processing its sales data for the week.
