"Paris was a really difficult time for me, but I thought, I cannot go back to my hometown with nothing, I have to at least make some money. But it was impossible so after about six months I went to Barcelona, and that's where I made my first money."
Although she has built up a thick skin thanks to her rocky start in the industry, Irina insists she is not a "mean" person but puts her "straightforward" manner down to her Russian upbringing.
She explained: "Some people think I'm not nice. I mean, I'm Russian and I can be really Russian but I'm a very friendly Russian. I'm a pretty nice person, but sometimes people don't know that about me. I'm very straightforward - if I like you, I like you, if I don't like you then do not even try to come near me."
And despite having become a world famous model Irina - who is dating actor Bradley Cooper - admits she still finds her career "difficult".
She told the Daily Telegraph newspaper: "It's a difficult business, it's very competitive. People who don't know our life think, oh, she's pretty, she's wearing a pretty dress and she smiles and she gets paid a lot of money for nothing, but it's a hard job."
