Keith Urban rushes from the Grammys to be by sick Nicole Kidman's side

Keith Urban rushed home from the Grammy Awards because his Australian wife, Nicole Kidman was ill.

The couple typically support each another at high-profile events but the 52-year-old country star had to walk the red carpet alone at Los Angeles' Staples Center on Sunday as the Big Little Lies star has been suffering from flu and he was keen to get home to nurse her.

"My wife is home with the flu. A lot of that going around,” he told PeopleTV.

Keith – who was at the event to present the evening's first award, Best Pop Solo Performance, alongside Cynthia Erivo – was grateful his wife was in "good hands" at home with their kids Sunday, 11, and nine-year-old Faith.

He added: "She's home with our girls tonight and I'm heading home ASAP."

This isn't the first time Keith has walked a red carpet without Nicole, as last June he admitted he "missed" her by his side when she was forced to skip the CMT Music Awards in Nashville, Tennessee, because she was working in New York.

The Somebody Like You singer dedicated his acceptance speech for Best Collaborative Video of the Year, for Coming Home with Julia Michaels, to his other half.

"My wife, Nicole Mary, who's at home tonight. "[She's] working in New York, actually,” he said.

"I wish you were here, baby girl. I miss you."

Asked what Nicole was working on, Keith later said: "She's shooting a project. I'm heading up tomorrow."
