Say it ain't so!
That was the reaction many pop culture fans had after E! News confirmed Rachel Bilson and Hayden Christensen had broken up after nearly 10 years together.
"They have very different lifestyles and interests," a source explained to E! News. "Rachel is very social and likes to hang out with friends. Hayden is reclusive and off the grid. She accepted that for a long time, but sometimes it was a lot to handle."
During their decade-long romance, the couple welcomed a daughter named Briar Rose Christensen. But throughout the love story, these two tried their best to stay out of the public eye.
Sure, they attended special red carpet events such as the premiere of Jumper. And yes, they enjoyed date nights every so often at sporting events and Los Angeles restaurants.
But unlike so many famous pairs in Hollywood, this duo kept their romance private.
"It was a gradual buildup of issues and problems," a source shared with us when explaining the breakup. "They were in agreement it was time to move on as a couple."
Instead of mourning the loss of another beloved couple, we decided to compile some of their greatest pictures together in our romance rewind gallery below.
Whether attending friend's wedding receptions or award shows together, there was something about these two that so many fans couldn't help but love.

Presenting One Special Pair
Back in 2007, Rachel Bilson and Hayden Christensen stepped out for Spike TV's Video Game Awards at Mandalay Bay in Las Vegas.
Red Carpet Pros
One year later and the pair would attend the premiere of Jumper at the Ziegfeld Theater in New York City.

Talk about a power couple. Both Rachel and Hayden delighted fans when they attended the Costume Institute Gala Benefit at The Metropolitan Museum of Art in 2010.
Fun in the Sun
Every couple needs a good vacation. And in 2013, these two joined friends for a relaxing getaway to Barbados.
All Dressed Up
While attending George Lucas and Mellody Hobson's wedding reception in 2013, this pair couldn't help but look madly in love.

During a trip to Cannes, France in 2013, the couple attended the Glacier Films launch party aboard the Yacht Harle.
Forget about red carpet Hollywood-type parties. Sometimes, Rachel and Hayden just wanted to attend a Los Angeles Kings hockey game at Staples Center in Los Angeles.
Look of Love
While they didn't post pictures of themselves on Instagram often, when they did, it was so sweet.
In a rare public appearance, the famous couple stopped by Du-Par's Restaurant & Bakery in Studio City, Calif., before heading home.
Perhaps we should enjoy some old episodes of The O.C. to get over this breakup. Maybe we need to watch Anakin Skywalker in Star Wars again.
Whatever the case may be, we're going to miss seeing these two together.
