From Kimye and Brangelina to Tiger Woods and Lindsey Vonn, these 13 couples were all over the news -- and each other -- in 2013
Kate Middleton and Prince William
Thanks to Middleton's pregnancy, and the subsequent birth of baby Prince George in July, interest in the Duke and Duchess of Cambridge soared to levels not seen since their April 2011 wedding. Royal baby mania took over the world, as people followed the couple's every move, from George's first photo op to his October christening. No other baby -- except maybe North West -- inspired such fascination and fandom in 2013.
