Actress Lena Dunham has gone public with a sweet email love letter she sent to her pop star boyfriend Jack Antonoff as part of a new art project.

The Girls creator and star was among the celebrities who allowed filmmaker Miranda July to browse their email inboxes for her online collection, We Think Alone, which gives fans a chance to peak at private correspondence belonging to 10 public figures.

Dunham previously shared a message from April (13), when she almost purchased a $24,000 (£15,480) sofa from Sweden, only to change her mind and tell her assistant the furniture was "just too expensive".

Now the actress has allowed July to use a note intended for fun. star Antonoff, which was written last year (12) during a family trip to India.

In the email, she wrote, "I was walking through a beautiful Indian garden this morning... and passed a big green pond with a dozen disorderly swans.

"All the old people in my party were cooing about the swans but I was focused on this young couple, late teens or early twenties, curled up on a bench talking really animatedly. We spent 40 minutes walking around the garden and when we circled back they were still there, chatting like fiends. And I thought of you, like always, and I felt I could spend four days on a bench with you and it wouldn't be enough time to hear all the stories you have to tell.

"I literally want to know everything you have ever seen and what you felt like while you were seeing it. And I will be so much better my whole life for knowing those things."
