Atlhough the two had been platonic friends, Kate Middleton first grabbed Prince William's romantic attention when she modeled lingerie in a school fashion show at the University of St. Andrews in 2002.
Kate and Will started dating soon after that 2002 fashion show, and the couple graduated St. Andrews in 2005. They broke up briefly in 2007, but reunited a few months later.

After dating for more than seven years, Prince William proposed on vacation in Kenya. The couple announced their engagement in November 2010.
The royal couple tied the knot in an elaborate London ceremony on April 29, 2011. Nearly 23 million Americans tuned in for the nuptials.
The couple wanted to start a family soon after marriage, but waited until after the Queen's 2012 diamond jubilee celebration to start trying so as not to take attention away from The Queen. (Getty Images)

After being released from the hospital, Kate made her first public appearance on Dec. 16 at the BBC sports awards show.

In February 2013, Italian gossip magazine "Chi" came under fire for publishing photos of Kate and William on vacation in Mustique. Kate sported a baby bump in her bikini, but the royal family was furious the photos were taken and sold. (Above photo taken from a 2011 vacation in Spain)
Kate and William made their last public appearance together before the baby arrives on June 15 at Queen Elizabeth's birthday celebration.
