The American star, who recently released his new single Who Dat Girl on iTunes, told UK newspaper Daily Record: 'I love travelling around the world capturing images and different countries and seeing people and watching the fans.
'I always make sure I get souvenir magnets and T-shirts to take back from my travels.'
The 31 year-old added that he's been trying to learn new languages so he can communicate better when he is abroad.
He said: 'It's great seeing my music in places where they don't even speak my language. That's been a highlight. It's interesting learning the languages a little bit. I know a little bit of Japanese and a little bit of French now.'
