Usher has over 10,000 pairs of shoes.
The R'n'B singer admits he knows his footwear addiction is "ridiculous" but can't stop himself from splurging out on new pairs.
He said: "Yeah, it's true. I even ask myself, 'Are you serious?' It's ridiculous. I go from Timberlands and Hi-Tec to Balenciaga and Lanvin. I have someone going to pick up the new red Nike Jordans for me right now."
The 30-year-old star - who is in the process of divorcing his estranged wife Tameka Foster, with who he has two sons - also has an addiction to unusual watches.
He added: "I own about 80 watches. I travel with at least four. They're not all high-end.
"They range from Cartier and Rolex to Seiko and G-Shock. It's about what suits me at the moment. I also have hundreds of suits. Designer Tom Ford fits me really well."
Despite splashing out on array of expensive, designer accessories, Usher says his life had more purpose when he became a father and he is now more careful with money.
He explained: "Before, everything was about accumulation and conquering. Kids give you more purpose. Now it's about transferring the wealth.
"I've got to take care of my babies. I want them to know Dad cared for them, nurtured them."
