Mark is now selling snacks & coffee from a catering van.
The 34 year old has set up his own catering business. He travels round festivals with his van and he serves customers food and drinks himself from the back of his truck.
When asked about it, Mark said
"It's going really well, we've got loads of interest and we've booked it in with a lot of the music festivals and we're talking about doing some Irish ones as well. People were flabbergasted at the fact that I was in the van making crepes. People kind of have this thing 'Oh, he was in Westlife a few years ago and now he's making tea. It's my business and I love it, anything I get involved in I get involved 110%."
Mark says he hasn't given up on music yet though and is planning to launch a solo career. Westlife disbanded in 2011 after 14 years together. During their career, they notched 26 top 10 hits.
