The 32-year-old Girls star shared a selfie of herself and her former musician beau getting cozy on Friday night. In the snap, Antonoff is smiling and looking at a screen, while Dunham rests her head on his shoulder.
"Best friends 4ever," the Lenny Letter co-creator captioned the sweet Instagram pic that shows that they're still friendly exes. The 34-year-old Bleachers singer-songwriter and Dunham called it quits in January after five years of dating. At the time, the actress' rep, Cindi Berger, told ET that "the breakup was amicable."
“Normally I would never address rumors,” he wrote on Twitter. “But I resent having the most important friendships and working relationships in my life reduced to dumb hetero normative gossip. Those relationships are deeply important and sacred.”
He then clarified, “With that said, I’m not seeing anyone. Lol.”
"We sat in our shared kitchen of nearly four years and quietly faced each other, acknowledging what nobody wanted to say," Dunham wrote. "That obsessive connection had turned to blind devotion, and the blinders were coming off to reveal that we had evolved separately (the least shocking reason of all and perhaps the most common). That anger wasn't sexy or sustainable. That our hearts were still broken from trying so hard to fix it but no longer uncertain about whether or not we could. The finality nearly killed me, and I remember muttering, ‘But what if we still went on dates?' He laughed sadly. ‘Whatever you want.'"
