Justin Bieber's music has inspired a collection of nail polish - but the 16-year-old singer says he won't be wearing any of it.
"It's not really my nail polish line. Like, I think it's weird to think about that," he said.
Justin - who was promoting his autobiography, First Step 2 Forever: My Story - says the nail polish from Nicole by OPI, which is set to hit stores next month, is inspired by his hit songs.
"Like, there's names like named after my music," he said.
"I don't know," he added. "It's like a really weird concept."
The collection, called One Less Lonely Girl, is set to include a bright red shade called OMB! and a glittery polish named Step 2 The Beat Of My Heart.
The impetus for the nail polish line was OPI's willingness to donate to Pencils Of Promise, a school-building organisation Justin has supported before.
Justin said: "A portion of it goes to charity, so that's always good."
The star added he looked up to Justin Timberlake and Usher for inspiration, because he admires the way they have become successful adult artists.
He said: "I see myself making a smooth transition from being a teenage heartthrob to an adult singer. I want to make that smooth transition, kind of like Usher or Justin Timberlake did it."
