The One Direction singer praised model Eleanor Calder, who he has been dating since September last year.
"Eleanor's really down to earth," Tomlinson told new magazine.
"She makes me fish finger sandwiches and it's great to do something normal after the madness of the tour.
"All my mates are at university, and it's a life I haven't had a chance to enjoy, so it's great to turn up and sample a bit of it."
Tomlinson was recently angered by One Direction fans targeting Calder.
