The Russian model, 35, has graced the cover of the US Elle magazine and also spoken about raising her daughter with Lea De Seine with Hollywood actor Bradley.
Irina told the magazine: "I never understood the term co-parenting. When I'm with my daughter, I'm 100 percent a mother, and when she's with her dad, he's 100 percent her dad. Co-parenting is parenting."
She also described Bradley as "the most amazing dad" to their daughter.
The model also revealed why she and Bradley have remained so private about their relationship.
She explained: "My past relationship, it’s something that belongs to me, and it’s private.
"It's just a piece of my inner self that I don't want to give away.
"I don't read what is out there. Honestly, I’m too busy raising a child. If they want to write articles [about me], they're doing their job.
"I'm concentrating on my life and my friends. The rest is just noise."
Irina first began dating Bradley in 2015 and went on to welcome their daughter in 2017 before finally splitting in June 2019.
It was reported that the pair's difficult work schedules were what kept them apart.
A source told The Sun on Sunday that Irina "loved the privacy she had with Brad" and loved that they had "lots of time for each other".
However, "both were working a lot as she travelled the world modelling and he spent long periods on film sets".
Irina revealed in an interview earlier this year that she spent her childhood feeling like she should have been a boy.
"I felt I was supposed to be a boy," she told British Vogue.
"Maybe it’s because my father always wanted a boy."
She added: "When my father passed away I thought, Since I’m a guy, now it’s my time to take care of the family'.
"Later on in life I outgrew that, and I love being a woman."
