There's no denying "I'm the One" is the song of the summer!
Putting her horseback riding skills to the test, the bikini-clad Playboy playmate was hard to miss in her music video debut.
Opening up exclusively to Life & Style, Iryna, who was discovered on Instagram, shared some of her favorite on-set moments and revealed what the Biebs was actually like behind-the-scenes.
"In my opinion, he was very nice and down to earth," she said of Justin. "He was not showing off, or anything like that. Actually, in fact, he was very shy. He wasn't really hitting on the girls or trying to get with any girl. He was just very nice and respectful, which I didn't expect."
In fact, it was Lil Wayne who was the most outgoing of the bunch, with Iryna adding that the artists, crew, and about 30 other girls were on the Malibu set from 7 a.m. to 10 p.m.
As expected, following her cameo, which is being compared to Emily Ratajkowski in "Blurred Lines," the brunette beauty has seen her social media following grow (she currently has over 2 million followers on Instagram alone). However, with the good comes the bad.
"There's definitely positive and negative," she explained. "There's always going to be negativity the more fans you gain. However, for me, it was a great experience, I've never done anything like this and I regret nothing about it. I would do it again one hundred times."
