Adele's 25 has already sold at least 2.3 million in pure album sales in the U.S., according to Nielsen Music, and she's poised to top close to three million before the official chart is released over the weekend (29Nov15).

25 is already only the second album to sell more than two million copies in a single week since Nielsen Music began tracking sales in 1991, and it appears it will sail past 'N Sync's single-week sales record for No Strings Attached, which debuted with just over 2.4 million in March, 2000.

Meanwhile, Adele also rules the U.S. pop charts for a fourth week with Hello.

The single keeps a surging Justin Bieber off the top of the Billboard Hot 100 - the pop superstar has three songs in the new top five, including Sorry, which returns to the number two spot. Bieber's What Do You Mean? also returns to the top five at five, while Love Yourself debuts at four.

Bieber is now one of only three acts to chart at least three songs in the top five at once - the Beatles managed the feat in 1964 and 50 Cent also featured in the top flight for two weeks in 2005.

Bieber makes additional history with a record 17 songs on the Hot 100 simultaneously, passing the mark of 14, previously held by the Beatles and Drake.

Bieber is also currently number one in the U.S. album charts after seeing off a challenge from One Direction over the weekend (22Nov15). His new release Purpose beat the boy band's Made in the A.M. to the top of the countdown with sales of 649,000 equivalent album units. One Direction's Made In the A.M. debuted in second place with 459,000 units.
