The blonde beauty has confessed she can't keep up with her model pal's hardcore kickboxing regime and is too afraid to take her on in the ring.
She said: ''I couldn't keep up! I watch Gigi, and I'm terrified of her. If I snuck up on her and scared her or something, she would kill me!
''She's learning things that should be illegal, like crazy! [Kickboxing] terrifies me - I'm like a softy in the corner doing yoga while these girls are breaking boards with their heads.''
The 19-year-old model is more than happy to leave the adrenaline fuelled workouts to Gigi and enjoys sticking to non-violent exercise routine's instead.
She said: ''I hate violence, I hate hitting things, so I never got down with kickboxing. I'm a dancer, so I'm a barre class girl. I love like Physique 57 and Cardio Barre; that does more for me. My friends and most models swear by kickboxing, and I just look at them like, you're crazy!''
Meanwhile, Ireland is putting her modeling career on hold while she tries to make a name for herself in the movie industry and the California-born beauty is struggling to get used to the idea of moving to New York City to pursue her dream.
She told E! News: ''I have a few things coming up that I can't really discuss at the moment yet, but that's why I'm going to New York. I've been focusing on acting lately, and that's why I've stepped out of the modeling spotlight to be in film school. I just switched actually - I'm looking into New York Film Academy right now.
''I hate New York. I absolutely hate New York, so I'm pushing myself to do it!''
