SUMMER OF LOVE
The romance begins to heat up for Julianne Hough, 24, and Ryan Seacrest, 38, who are spotted getting cozy all over Los Angeles in the summer of 2010, nearly three years before they announced their split on March 15. "They're perfect for each other," a source told PEOPLE in June. A month later, the freshly minted lovebirds take their relationship overseas to Italy, where they board their own personal love boat.

After hushing engagement rumors, the couple jets off for a sweet escape in November. On their itinerary? Paris, where they take in the restaurants, art galleries and shops of the City of Light, and even squeeze in some time with Seacrest's parents and sister for Thanksgiving.

HAND IT TO THEM
Summer turns into fall with a trip to Chicago, a healthy dose of partying, and a string of both romantic and family dinners. "It's a hard thing to do, especially when you're so caught up in your work and bettering yourself," Hough told Parade in February 2012 of juggling a career and a relationship. "I think at the end of the day, you have to find a balance with what's really important."

Call it puppy love: Seacrest even wins over Hough's biggest (and cutest) fans: Cavalier King Charles spaniels Harley and Lexi, who share their mom's attention on a May 2012 stroll through N.Y.C. One month later, Hough tells Seacrest "love you" on-air during a call-in to his KIIS-FM radio show.

GET ON BOARD
Amid the start of red carpet season and a promo tour for Hough's latest drama, Safe Haven, the couple pushes their jam-packed schedules aside in January 2013 to head to the Caribbean island of St. Barts – where the only thing looking blue was the water. "When we do see each other, we are super excited and do these cute and romantic things," Hough told InStyle. "I'm 20 lbs. heavier than I was when we started dating."

Even amid a who's-who crowd of Hollywood's biggest stars at the 2013 Golden Globe Awards, Seacrest has eyes only for his leading lady, whom he called "absolutely beautiful," in what becomes one of their final public outings together.
