One of Hollywood's most stable and adorable couples is no more.
In very surprising news, Lena Dunham and Jack Antonoff have decided to go their separate ways.
The actress/writer/producer and the singer/songwriter actually broke up in December, according to E! News insiders, following five long years of dating.
"It was mutual," this outlet's main source says, adding simply:
"Jack and Lena were growing apart and it just made sense for them to end their relationship where it was."
This seems pretty hard to believe, of course.
We're not saying there was any cheating or anything especially ugly took place between the stars.
We're just saying break-ups are rarely truly mutual, especially not for the vague reason of just "growing apart."
The Girls creator and the Bleachers frontman met on a blind date set up by Antonoff’s sister and comedian Mike Birbiglia back in 2012.
This blind date went so well, the musician quickly told Dunham everything about himself, “because when you really like someone, you want them to know everything about you,” Antonoff explained in 2014.
Not long afterward, Antonoff moved in to Dunham's home in Brooklyn.
While each has referenced the other at various point in the past few months, the last time they attended a public event together was nearly a year ago; at a pre-Grammys party in early 2017.
In October, though, the actress wrote an essay about her now-ex-beau for Variety.
It partly read:
"It's safe to say that before Jack my life was full of far fewer sights. He showed me the importance of making political statements using your public platform. He showed me the joy of collaboration."
Despite this clear connection, though, Dunham always made it clear she never saw herself marrying Antonoff.
Perhaps that should have been a sign right there that the very long-term future was bleak, although Lena did often say the two would exchange vows once gay marriage was made legal in the United States.
But then this happened in 2015.
And still... no ring.
Speaking with People Magazine last June, the artist said his life at home with Dunham is “pretty normal in terms of everyday life."
He went on to describe their romance as two people “trying to support each other [and] trying to find something new and exciting for dinner.”
So... where did things go wrong?
We don't know. All websites that have reported on this break-up agree the split was amicable and that the stars will keep in touch.
"They want the best for each other no matter what. They are both moving on," the E! News source concludes.
We're glad to hear it.
While it's far more fun for a celebrity gossip website to write about some seedy reason for a relationship ending, it's far more encouraging from a human being standpoint to know people can break up and not hate each other.
