Watch: Westbrook explains why his mom is his style icon

Russell Westbrook isn't afraid to admit that he still turns to his mom for fashion advice.

Appearing on "Good Morning America" on Wednesday to promote his new book "Style Drivers," the Oklahoma City Thunder star named his mother, Shannon Horton, as his style icon.

"She's always swagged out," he explained. "She's always kept me up to par on the fashion, on the style, and to this day, I can still call her and she can give me a yay or nay."
