Justin Bieber – OPI Nail Polish, Estimated $12 Million

Justin Bieber broke thousands of hearts when he got married to Hailey Baldwin, and we can’t blame him! The child pop star is still known for his amazing vocals and a gorgeous smile.

In 2010, then 16-year-old Justin Bieber was paid $12 million by OPI to design an exclusive nail polish collection. Since the singer’s massive audience is mainly made up of young girls (OPI’s target demographic), the partnership was beneficial to both sides. The superstar’s young age made him one of the youngest highest paid endorsed celebrities in the business. His collection “One Less Lonely Girl” is considered one of the brand’s most successful lines in recent years.
