The royal wedding is happening in a week, and all the networks are gearing up with special documentaries on Kate Middleton and Prince William. One of these, “The Women Who Would Be Queen,” is anchored by CNN’s Soledad O’Brien, and examines the full history of the relationship between the future heads of the UK’s Royal Family, as well as Middleton’s life in the shadow of Princess Diana. O’Brien journeys to the sceptered isle and chats to a flurry of friends, confidantes, unauthorized biographers and inner-circle members, who dish some intriguing dirt. (Did you know that William attempted an online fling with Britney Spears?” Below, see a clip of the couple’s university friend discussing what Prince William and Kate were like in college (and what it was like to party with William). And watch the full documentary on Sunday, Apr. 25 at 8 PM ET.
