SINGER Donny Osmond has said he still enjoys performing his hit Puppy Love and believes pop stars should treat their early chart-toppers with more respect.

The former teen idol admitted he rejected the song at one point because he did not want to be pigeon-holed but now he is grateful to have enjoyed such success.

Osmond, 59, said: “Puppy Love is probably the most recognisable song to a certain generation so why turn away from it? I did for a while but I realised it made me who I am today so why would I turn a blind eye to something so successful?

“Maybe one day Justin Bieber will sing Baby [his first big hit] with more respect.

“I understand what he’s going through though, when you start at such a young age and you get put in a box and want to back out.

“Justin Timberlake was in N Sync and did that silly stuff in a boyband, the same thing applied to me.

“It’s 45 years I’ve been singing that song, in a different key now mind you.”

The singer found fame in the 1960s with his older brothers as The Osmonds, and then enjoyed a smash hit as a soloist with the ballad in 1972.Osmond still performs it every night in his hit Las Vegas variety show with his sister Marie and said it reminds him of when he was at the height of his fame.

He said: “It’s a great memory, being in London in the 70s. It really does remind everyone of those innocent but hysterical years.”

Donny Osmond’s The Soundtrack Of My Life UK tour will kick off at the Manchester Arena on January 21, before travelling to Glasgow, Brighton, Cardiff, Nottingham, Liverpool, London and Birmingham.
