Meanwhile, Kate Upton talked about how she started modeling at an early age and how lonely things get when she has no one to be with while she is travelling.

She said: "I started working abroad when I was 15 and my mum and dad would often come. The thing is with modeling, you don't actually need someone there; it just gets lonely.

Though she is used to travelling including dealing with the customs, getting a taxi and going to hotels, she said that she sometimes gets bored.

"It's not fun to hang out with yourself for days at a time. It can be a solitary profession," Kate Upton explained.
