It's true: After more than five years together, Lena Dunham and Jack Antonoff have officially called it quits.

According to E! News, the couple split up in December. The break up wasn't messy and was mutual. "Jack and Lena were growing apart and it just made sense for them to end their relationship where it was," a source told the outlet. "They want the best for each other no matter what. They are both moving on."

The actress and Bleachers mastermind got together in 2012, after being set up on a blind date. "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," Dunham penned in an essay for Variety three short months ago.

Two months ago, the Girls creator actually thought she overheard her ex planning a proposal with his sister. "I thought Jack was furtively planning a proposal to me with his sister and he just admitted I actually caught him 'talking s--t' about me!" she revealed on Twitter, before explaining how totally fine she is about him not popping the question.

The couple has yet to publicly address the break up.
