Justin Bieber has been offered words of wisdom from New Kids On The Block veteran Joey McIntyre.
The star, who shot to fame with the US boyband when he was just 13, said 16-year-old pop sensation Justin had to stay grounded and not forget that there was more to life than performing.
"Hopefully kids like Justin... there's a lot of young artists out there, and hopefully they've got good family around them and they're able to take the ups and downs," Joey told Entertainment Tonight.
"You gotta learn how to hang in there and know that there's so much more to life than just singing pop tunes and dancing around on stage. And that takes a while," he said.
"Everybody's got their own path and their own time. You have to go with the flow and learn some things the hard way."
Joey admitted he found it difficult to deal with the highs and lows of stardom at such an early stage.
He revealed: "We weren't perfect. We certainly made mistakes, and there were dark days. You're the biggest thing in the world (but) you gotta come down. What goes up comes down, for whatever reason."
