Jay-Z and Beyonce

It must have been thrilling for the A-list power couple to secretly exchange vows in front of a close circle of 40 friends and family members including Gwyneth Paltrow, Kelly Rowland, Michelle Williams and Chris Martin at Jay-Z's penthouse in New York City in 2008.

Six months later, Beyonce told Essence magazine that she didn't want an engagement ring because: 'People put too much emphasis on that - it's just material and it's just silly to me.'
