In speaking to Out, they discussed getting engaged.

“We were so busy making all these plans – we both wanted to have children; we both wanted to build a home of our own someday. I draw, so I was sketching little plans for houses on cliffs overlooking oceans, while Tom watched over my shoulder – it was a very grown-up version of playing house. Marriage is the foundation to all of these other big plans we have. So we knew we were going to get engaged – it was just a matter of when, and who does it,” Black said.

Daley said that the first person he called after getting engaged was his mother.

“I had the ring box in my underwear, and when he came out of the bathroom, I just went down on my knee and proposed. Then he ran off to the bathroom to get his rings, and he had this whole speech prepared, but he’s a writer so his was quite extravagant. But looking back, all I can remember is being completely overwhelmed, like, Oh my God, we’re now engaged. Who do we have to call? So I called my mom, and he called his stepdad.”
