Ariana Grande has been "so deeply kind" to Rachel Zegler

Rachel told Allure: "She reached out to me - kind of apropos of nothing - and was like, 'If you need anything, I am here.' She is so deeply kind.

"She has gone through so much in the public eye, and I have always really, really admired her courage in the face of all of that."

The 'West Side Story' star has also received support from the likes of Jameela Jamil, Dame Helen Mirren and Lucy Liu.

Rachel said: "Jameela Jamil is like a big sister to me. I love that she has no regrets about being outspoken, about being strong-willed and strong-minded."

The actress doesn't subscribe to the idea that female stars are in competition with each other.

Rachel - who stars alongside Gal Gadot in the new 'Snow White' movie - said: "All I'm ever really looking for in this business is a sister and they're not always easy to find. We're often told that other women have to be your competition and I don't subscribe to that.

"I really do believe in championing your friends and championing your coworkers, whether you're close with them or not. So the second that there's any intimidation or competition, just put on 'Girl, so confusing' by Charli XCX and talk it out. I've come to know that in the last couple of years, in search of female friendship in the industry, there is room for all of us no matter what anybody else will have you think."
