Before Louis found global fame in One Direction on the X Factor in 2010, he was a budding actor with a string of background roles.
As well as Waterloo Road, Louis had appeared in Kay Mellor's Fat Friends, alongside James Corden and Lisa Riley, and the drama film, If I Had You.
Earlier this week, while speaking to Scott Mills on BBC Radio 2.
He said: 'I did work at Toys R US. It was one of my favourite jobs. I absolutely loved it. I loved it. Honestly. I was just on the tech.
'I had to just do the tech basically, giving tech demos to people. Do you remember Guitar Hero? Well, they'd just released DJ Hero.
'I just spent hours on my working day demonstrating to other customers. I loved that job though, I loved it.'
It comes after Louis sparked concern by sharing a string of tweets admitting he's 'terrified' of touring, after taking a public swipe at when their music dropped on the same day.
Sources told Daily Mail in January that the star How Did I Get Here?.

The star said he's got a 'really really good feeling' about his upcoming shows, but confessed he had been 'hard on himself' about shows in the past, sparking many fans to share messages of support.
Louis had previously shared that he needed his fans to rally to give his new album 'the moment he deserved,' after it dropped on the same day as Harry's new track.
Harry and Louis's relationship has been complicated over the years, though both have denied rumours they fell out when One Direction split in 2016.
In his posts, Louis said: 'Right listen, heart to heart, I want to level with you all. I know I haven't been as present online as I have been in the past. Been taking a bit of time for myself but I can't express the incredible gratitude I have for all of you!
'Feeling so so so f*****g excited for this tour. Weirdly it all hit me today. Just went down to crypto arena to do a few bits and feel so proud of how far we've come...
'These moments are going to be the most pure, special and visceral yet. I can feel it... Feeling incredibly sentimental today...
'My first tour was so f*****g terrifying to me and maybe because I was pretty hard on myself, weird little paradox every night of feelings the adrenaline and the love of the crowd all the while scolding myself in my head. I had some incredible shows that tour and proved a lot to myself but still it was a tough one mentally...
'The 2nd tour had a different energy about it. I felt much more assured in the music in an album that was literally designed for the live show but I'd be lying if I said I didn't have some nights where I questioned myself.
'About midway through that tour I remember metaphorically looking in the mirror and saying to myself that I needed to allow myself the success and the idea of being capable on my own.
'Gratitude is an incredible feeling but also comes with its own pressure, I wanted so much to deliver for you all every night and wasn't allowing myself room for error. That momentum shift was really important for me.
'The last show of that tour absolutely blew my f*****g mind, it gave me room to reflect on how far I'd come. Never did I imagine WE'D be able to achieve this...
'And now here we our about to start the third tour. I've got a really really good feeling about this.
'That's not some b******t marketing ploy to make you come to the show, I genuinely haven't ever felt this assured about the show we're about to put on.
'If you're reading this and you're a fan, don't underestimate your importance in how I feel professionally. Now if I'm real with myself I'm sure there will be a few moments where I get in my own head but after all these years I feel so protected by you all in those spaces.
'I literally can't f*****g wait for these shows. Will it be a performance worthy of a vocal Olympian? No Will it be the best selling show of the year? No
