'N SYNC stars congratulate Adele for breaking their album sales record

The stars of 'N Sync have saluted Adele for breaking the boy band's 15-year single-week album sales record.

The Brit passed the group's 2.4 million sales mark with her new album 25 on Tuesday (24Nov15), and Lance Bass, Joey Fatone and JC Chasez were among the first celebrities to congratulate her.

"Records were made to be broken," Chasez says. "It was a flattering luxury knowing we sold more records than anyone in a week but it's also nice seeing people continue to be passionate about music in the next generations. Adele proves that emotion and art are alive and well in music today."

His bandmate Bass took to social media to offer his thoughts, adding, "We officially say Bye Bye Bye as @Adele says Hello to the World Record of Most Albums Sold In a Single Week. Congratulations!!"

And Fatone revealed he was among the 2.4 million fans in America who bought 25 upon its release on Friday (20Nov15).

"Records are always meant to be broken, but with technology and current music business model, I thought this one would be tough to beat," Fatone told Billboard. "In all honesty, Adele is the truth - kinda excited a rare talent like hers is in the same breath as our group. I'm a huge fan... I even bought the damn album!"

Adele's 25 is projected to sell 2.9 million units in its debut week, with experts suggesting that 42 per cent of all U.S. record buyers have picked up a copy.

'N SYNC's second studio album, No Strings Attached, debuted in 2000, moving 2,416,000 units for the week ending 26 March. Adele's new release matched that amount in a little over three days.
