Ciara's friendship is foundation of a great relationship with NFL star Russell Wilson

The 31-year-old star, who is married to National Football League star Russell Wilson, says: "I really believe that when you focus on a friendship, you have the opportunity to build a strong foundation for a relationship - and once you know you're really great friends and you're what we call 'equally yoked,' where you share the same values or the same outlook on life, it kind of sets the tone," she was quoted as saying by Femalefirst.com.
