ET has learned that the 31-year-old journalist is engaged to Barack Obama's former speechwriter and Pod Save America host, Jon Lovett. The two were first romantically linked in 2011, and Farrow posted a sweet birthday message on Instagram for Lovett back in August.
"Happy birthday to straight shooter respected on all sides @jonlovett. He’s OK, I guess!" he wrote.
In Catch and Release, Farrow seemingly reveals how he proposed to Lovett as he was helping him with drafts of his book.
“Later, when I decided some of that reporting would make its way into a book, I’d send him a draft, and put in a question, right on this page: ‘Marriage?’” he writes. “On the moon or even here on Earth. He read the draft, found the proposal here, and said, ‘Sure.’”
