Lena Dunham has broken up with her boyfriend of 5 years, Bleachers frontman Jack Antonoff.
The former couple first met on a blind date in 2012, and broke up in December. An insider said, "It was mutual. 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 both moving on."
A rep for both stars has confirmed the split.
