Seward says the Queen is convinced that a main reason Fergie's and Diana's marriages failed is because they came from broken homes. The fact that Kate is a commoner is not a problem for the Queen, she says.

"I think she is very happy about Kate having this loving, close family," says Seward, who notes that the 85-year-old queen wants to see the future of the institution of the monarchy secured and says she feels with William and Kate it can be achieved.

Seward shares details about the VIP guest list, the fashions of the day, Prince Harry's best man speech and the wedding price tag Friday, April 29 at 8 p.m. ET as "CBS Evening News" anchor and managing editor Katie Couric takes you inside the day's most intimate and historic moments live from London in CBS News' primetime special "The Royal Wedding: Modern Majesty."
