Joe Swash is probably best known for his appearance in EastEnders, playing the cheeky chappie Mickey Miller.
But the ex soap star, 38, baffled parents when his very recognisable voice popped up in a popular kids' TV show.
It turns out that Joe is actually the voice behind the character Sonny in the Thomas the Tank Engine spin-off series Thomas & Friends.
Sonny is a navy blue train with gold lining and white boiler bands, and a black buffer beam with red sections.
Thomas & Friends follows a group of trains living and working together on the fictional Island of Sodor.
Joe has been part of the series since last year.
His first well known role was in EastEnders, which he joined in 2003 and left in 2008.
The TV star then returned for two episodes that aired in 2011.
In 2008 he won I'm A Celebrity... Get Me Out Of Here!.
Then in 2020 he became the unexpected champion of Dancing On Ice with his skating partner Alex Murphy.
In 2015 he started dating Stacey Solomon after meeting on the I'm A Celebrity spin-off show, Extra Camp.
The couple welcomed their first child, baby Rex, in 2019.
On Christmas Eve last year Joe proposed to Stacey on a romantic walk through the woods near their home, which she said is her favourite place.
They are planning to marry later this year.
