Stars like Miley Cyrus and Justin Bieber will regret their behaviour in years to come, says 1970s pop idol Jimmy Osmond.
The 51-year-old was part of the seven-strong family group The Osmonds, one of the biggest bands of that decade.
But in an interview with the BBC's Sunday Morning Live show, Osmond said family values had protected the siblings from the pressures modern pop singers face.
"I think nowadays we reward bad behaviour because it's good business for the media," he said.
"I think if you really look at maybe Miley Cyrus and the core of her and the core of Justin Bieber, you see some good kids just trying to figure it out to stay on top because there's such pressure when you're up there."

Osmond says the acts feel such pressure that they'd "have to almost shock people to stay in the mainstream".
"They have a responsibility. They're affecting young teenage minds that this is good behaviour, and someday they're going to look back at that and regret it."
Osmond said he was grateful he had a family that guided the band "to conduct ourselves without taking substances into our bodies".
He said the pop heartthrobs had lived without alcohol, drugs or sex before marriage.
The Osmonds, a family from Utah in the United States, began as a barbershop quartet in the late 1950s and scored their first American number one single in 1971.
