MORE: Gavin and Stacey star Larry Lamb just gave a major update on show's return - and fans will be pleased!

The hit BBC sitcom saw Nessa, played by Ruth Jones and Smithy, James Corden, welcome a baby boy together – but fans never got to watch him grow up before the show ended in 2010. Viewers might also be surprised to learn that there was actually more than one actor that played Neil on the show.

Lewis Merchant, now twelve-year-old, played Neil in the 2008 Christmas special of the show, while Ewan Kennedy and Oscar Hartland played Neil in various parts throughout the series. Oscar even returned as an older Neil in the 2019 Christmas special! See how much they've grown below.

Oscar played Neil in the original series and the 2019 Christmas special

Meanwhile, Oscar recently enjoyed reprising his role as Neil in the most recent reunion of Gavin and Stacey which debuted on Christmas Day in 2019. The young actor auditioned and was lucky enough to land the role, but revealed he "didn't get his hopes up".

During an appearance on Good Morning Britain ahead of the highly-anticipated reunion episode, he said: "I didn't really get my hopes up as there were other people who did acting. I was in a couple of newspapers and they noticed me. I did my audition in Cardiff. A few weeks later I found out I got the job. It was really cool."
