RadioTimes.com spoke exclusively to Lia ahead of launch about her interactions with Kyrgios during filming for the show.
She said: "Nick Kyrgios is probably a different guy on court than he is off court. That was certainly our experience. All we can show is what we experienced and what we saw first-hand.
"He is someone that is going to be divisive. Even people in our team don't necessarily agree!
"For those of us that spent time with Nick, he's a complex, deep, interesting character. He was always respectful to us and the team.
"It was really important to us, and you'll see this in the second half coming out in June, that we first show the headlines that people know, but then we go deeper and we tell a story.
"Hopefully that does who he really is justice. In terms of filming, he was great to work with."

Lia and the team struck gold by following Kyrgios on home soil at the Australian Open in 2022 as he astonishingly went on to win the doubles tournament alongside best mate Thanasi Kokkinakis.
"We learned as we went along how to film it and then doing justice to the stories," she explained. "You have to get a little bit lucky. We follow people who we think are going to be interesting.
"It was [the producer's] idea to follow Nick Kyrgios, but we had no idea that he would win the doubles. Until you know what's going to happen, you just have to try and plan what's not impossible to plan for."
