John Legend and Ryan Gosling are a couple of proud papas!
The Darkness and Light singer chatted with ET's Carly Steel at the La La Land junket in Los Angeles on Monday, where he revealed how he and his co-star bonded on set over their recent fatherhood -- Legend's first child with wife Chrissy Teigen, daughter Luna, was born on April 14, while Gosling and Eva Mendes welcomed their second, Amada, on the 29th of the same month.
"Amada and Luna were both born in April. We talked about it," the 37-year-old artist shared. "We had just announced that we were pregnant right around when we were filming the movie, so ... he definitely kind of shared how joyous it is to be a new father and gave me something to look forward to."
Though, while he and Gosling bonded over dad life, Legend confessed that Luna and Amada have yet to set a play date!
"They have not yet. She hasn't had a play date with anybody," he explained. "You can barely say she's had it with Andy Roddick and Brooklyn Decker's boy, Hank. But Hank is quite a bit older than her by a few months, so she hasn't really had a genuine play date with anyone her age just yet."
La La Land, which also stars Emma Stone, finds musician Legend stepping in front of the camera, and actor Gosling behind the piano, a mutual learning experience that Legend says brought the two closer together while filming.
"That made me feel a little bit more comfortable, that he was learning something new too and had that sense of... the struggle of a new thing," he said. "I was really impressed with him playing the piano, and I thought he was doing a really good job."
"I've been a fan of his work as a film actor for such a long time, so I was excited to work with him," Legend added. "I was just hoping that he didn't think I brought him down too much, knowing that he's been doing this for a long time and I haven't."
