AJ McLean has opened up about his struggles with addiction this week, in a truly heartwrenching story.

Who doesn't remember the Backstreet Boys?

The '90s boyband were basically the soundtrack to the decade.

The group consisted of Nick Carter, Howie Dorough, AJ McLean, and cousins Brian Littrell, and Kevin Richardson.

The super-successful group has sold over 100 million records worldwide.

In fact, this gives them the accolade of bestselling boyband of all time.

They're the first-ever boyband to achieve a number one hit in three different decades.

They are the first group since Led Zeppelin to have their first ten albums reach the top 10 on the Billboard 200.

Some pretty impressive stats.

But aside from their glittering careers, it seems there was tragedy behind the scenes.

And this week, bandmate AJ McLean has opened up about his past struggles - and how the band helped him out.
