Lena Dunham and Jack Antonoff have split.
E! News reported Dunham and Antonoff had drifted apart and that the pair's breakup was amicable.
"It was mutual," a source said. "Jack and Lena were growing apart and it just made sense for them to end their relationship where it was."
"They want the best for each other no matter what. They are moving on," the insider added.
"It's pretty normal in terms of everyday life," he said. "[We're] trying to support each other [and] trying to find something new and exciting for dinner."
Dunham said in a series of tweets in November that she mistakenly thought Antonoff was going to propose.
"Now I literally can't sleep cuz I'm laughing too hard and I am also keeping him awake. 5.5 years, no rock and you know what? It's real nice," the "Girls" creator said.
