Lena Dunham has reportedly broken up with boyfriend Jack Antonoff after dating for more than five years. 

A source close to the couple told E! News the break-up was a mutual decision, brought on by the Girls actress and Bleachers frontman "growing apart". 

"It just made sense for them to end their relationship where it was," the source said. 

Dunham, 31 and Antonoff, 33, are said to have split in December. 

"They want the best for each other no matter what. They are both moving on," the insider added.

Rumours the pair were on the rocks have been swirling since last year. Dunham tweeted in November that she thought Antonoff was "furtively planning a proposal to me…[and] I actually caught him talking shit about me". 

She followed it up with the tweet "5.5 years, no rock and you know what? It's real nice."  

In October 2017, the actress and social justice activist penned an essay about Antonoff for Variety. She wrote of her now ex-boyfriend; "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."
