Despacito (Remix) Luis Fonsi & Daddy Yankee feat. Justin B
Marcus Collins, last year's X Factor runner up, came to have a nice chat to Dan and Katy... And what a nice boy he was!
The guys chatted to him about being on tour, losing his voice, and the new single 'Seven Nation Army' - but he had to work to plug the album!
Dan and Katy played 'Slug It to Plug It' - basically, Budget X Factor Guy read out some song lyrics and Marcus had to identify the track. For every one he got right, he got 5 seconds to plug the album (which is out in a few weeks time).
Listen to how he got on below!
