Ahead of the episode tomorrow night, here's everything you need to know about Halimah and the Kyrgios family.

Halimah is the middle child in the Kyrgios family. She and her brothers, Christos and Nick, were born and raised in Canberra to Giorgos and Norlaila.

Their dad was born in Greece and moved to Australia as a child. He works as a house painter. While their mother, Norlaila, is a computer engineer with royal blood.

Born in Gombak, a district in Selangor, Malaysia, Norlaila's grandfather’s cousin was the Sultan of Pahang. This makes her, by birth, the Tengku of Pahang, which loosely translates to the princess of the Pahang state.

However, after moving to Australia in her 20s, Norlaila chose to give up her title.

After Nick Kyrgios won his match at the Murray River Open back in February, he opened up about his mother being ill.

"It’s not about me," Nick Kyrgios told reporters, referring to the controversy over tennis players needing to quarantine prior to competing in the Australian Open.

"My mum is incredibly sick. There’s too much risk in all of this. I don’t understand what’s so hard for tennis players to understand," he continued.

"Like, you’re just a tennis player. Do you know what I mean? It’s not life and death like this is."

Before auditioning forThe Voice, Halimah spent the past few years performing in musical theatre overseas.

Most recently, she starred in the Andrew Lloyd Webber musical,Starlight Express, in Germany, until the pandemic placed an indefinite hold on her career. After returning to Australia, she came across the opportunity to audition forThe Voiceand went for it.

Speaking to The Canberra Times, the 31-year-old explained that despite performing countless times before, the blind auditions were nothing like she'd experienced.

"It's a very different setting as to if you're just going to perform something we've rehearsed for hours, weeks, months, and you know what to expect when you go out there," she told the publication.

"Whereas for the blind auditions, you're sitting in the room with 200-plus people and you're just feeding off everyone's nervous energy. I was just going over in my head, the same things over and over again."

Both of her brothers are her biggest fans.
