Nick Kyrgios' sister wows The Voice judges with Blind Audition

Nick Kyrgios' older sister Halimah Kyrgios amazed fans of The Voice on Sunday night when she performed in the Blind Auditions, singing Tina Arena's 'Chains'.

Halimah wanted to show she's more than Nick's older sister, telling the cameras, "Growing up, we were always together.

"He was also singing and dancing, but he had a natural gift for tennis. I look to him a lot for inspiration. He's such a fighter, everyone knows that. He battles for everything. Even though he's much younger than me... If he can do it, why can't I? What's stopping me?
"I'm not very... out there like he is. Having Nick in the limelight has been a good and bad thing. There is added pressure. I really just want to focus on people knowing me as Halimah, not Nick's sister. That would be amazing to achieve."

When the 31-year-old performed the track, all of the judges turned around, stunned by what they had heard.

Keith Urban, Rita Ora, Jessica Mauboy and Guy Sebastian then found out she is Nick's sister and the tennis star is apparently not that bad of a singer and dancer himself, according to

Right after the performance, Nick appeared via Zoom with their parents.

I just flew back from Sydney so I missed it," he told host Sonia Kruger and the judges.

"She was amazing," Sonia responded.

"She always is," Nick said.

"It was even better than your shot through the legs, Nick," Guy teased the tennis star.

While she had all four judges to pick from, Halimah chose Rita Ora, saying she's a fan of hers.

I did not expect her to pick me, I'm really flattered. That's an Australian song, a classic and I'm glad she trusts me. There's a lot we can do together," Rita later told the cameras.

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.
