Justin Timberlake refuses to spend hundreds of dollars on his grooming routine - preferring to cut his hair himself.

The pop star insists that he doesn't need to indulge in unnecessary beauty routines to feel good about his appearance and is happy to avoid scissor-happy hairdressers.

He tells British magazine Heat, "I don't require hair or nail appointments. I actually cut my own hair - that's why it's all the same length."

And Timberlake hopes that revealing his down-to-earth routine will prove that he is more grounded than other celebrities.

He adds, "I don't like divas and I don't want to be one. People have a perception that I might be that way."
