OK! Old School: Happy Anniversary, Britney and KFed! A Look Back At Their Best Moments

In April of 2004, Britney and her new boyfriend, who was her backup dancer at the time, shared a beach day in Santa Monica. Lovin' the trucker hats, BTW.

Later that year in August once they were engaged, Britney and Kevin got swarmed by paparazzi at a grocery store. Only Ms. Spears would such a hoopla at ShopRite.

Milking their engagement (and Kevin's newfound fame), the couple had a date in Malibu just a few weeks before their fall 2004 wedding.

Two months after their wedding, the newlyweds looked happy as could be running some errands in LA.

In December of 2004, Brit and Kevin welcomed their first new addition—a puppy—and showed him off on the red carpet at the Billboard Music Awards.

Then the following summer in July, Britney and Kevin attended the premiere of Charlie & The Chocolate Factory where she wore a shirt saying "I have the golden ticket." Of course, this pun was referring to their baby-to-be, Sean Preston, who was born two months later.

In early 2006, Brit and Kevin hit up the awards show circuit together, cleaning up nicely for the SAG awards after party.

Then in February, the couple attended a Pre-Grammys party. Not lovin' this look though, guys.

They also attended a post-Grammys party together, just months after their son was born. Talk about losing the baby weight!

And in March of '06, Brit and Kevin attended a party for his birthday, which was the last birthday they spent together. Britney and Kevin announced their separation in November of 2006 when their second son Jayden James was just two months old. Thanks for the memories, guys!
