"The people we work with are just great and they're like family now. And, on the weekends, we go hiking, scuba diving, we see waterfalls, dolphins," she said.
On the special connection she has with her co-stars, she added: "We have a good time. It's not easy every day, because working with people every single day, from six in the morning to six in the evening, it can be quite long. So, we have ups and downs, it's normal we're human beings.
"But I've made very, very good friends, especially this year in series ten, I met amazing people. And we had so many great moments together."
