One of Hollywood's most stable, long-term couple is no more.
We must sadly pour one out for Rachel Bilson and Hayden Christensen.
After nearly a decade together - that's 10 years!!!! - the actor and the actress have gone their separate ways, sources confirm to Us Weekly.
One insider tells the tabloid that the split isn't exactly new. In fact, the couple hasn't even been living in the same country for several weeks now!
“She’s full-time back in L.A. He’s in Toronto,” says this insider. "They’ve been on the outs for a couple of months.”
Might they get back together, though?
There must have been very strong feelings involved if they were an item for such a long period of time, so perhaps a reconciliation is in the cards and this is just a non-romantic blip?
"They are completely, officially done," the source adds.
The stars met on set of their 2008 film Jumper and got engaged that December after a fairly brief courtship.
However, they quietly called off their engagement in August 2010... only to get back together three months later.
So there have been some ups and downs in the past, even prior to this apparent nail in their relationship coffin.
Bilson and Christensen are parents to a three-year old daughter named Briar Rose, who was born in October of 2014.
Their little girl’s name is a nod to the pair's mutual affection of Disney.
"There’s a Disney reference there I suppose," Christensen said during an appearance on Hallmark Channel's Home & Family in August of 2015, adding at the time:
"The original Sleeping Beauty is called Briar Rose. Rachel - we both love Disney - but Rachel especially was very keen on the name."
Bilson, of course, is best known for roles in beloved teenage soap operas The OC and Hart of Dixie.
Christensen, meanwhile, memorably played Anakin Skywalker in Star Wars: Episode II - Attack of the Clones and Star Wars: Episode III - Revenge of the Sith.
They didn't talk much about their romance over the years, but Bilson did gush over her man when chatting with Cosmopolitan in 2013.
"I'm a really good girlfriend - I always put all that first in my life," she said.
"I'm definitely the person who would make him his favorite dinner to come home to. I love to cook, so we make dinner at home a lot and watch movies."
Okay, so perhaps that more about herself than her man.
Maybe that should have signified there were problems at home, huh?
We wish these stars all the best as they go their separate ways.
