Pink's daughter Willow, 12, sings on stage with her proud mum – while son Jameson, seven, makes his debut on the first night of the star's Australian tour

Pink sent the crowd wild when she brought both her children on stage on the first night of her Australian tour on Friday.

The American singer, 44, has taken her epic Summer Carnival tour Down Under for a series of shows across the country and kicked off in style for her first show.

It was a very eventful first show at Sydney's Allianz Stadium, as Pink had to briefly interrupt the concert when a fan went into labor and was wheeled out by doctors.

Pink also shared some sweet moments with her own children Willow, 12, and Jameson, seven, who she shares with her husband Carey Hart, during the sold-out performance.

The global megastar, whose real name is Alecia Beth Moore, brought her daughter Willow on stage for the duet Cover Me In Sunshine.

Willow follows in her mother's singer footsteps as she wowed the audience with her talents as she confidently sang the lyrics to the song.

Videos from the concert showed Pink appearing emotional as she stood to the side of the stage and watched, with her daughter taking center stage during the song.

Pink was every bit the proud mother as she beamed from ear to ear as she watched Willow sing effortlessly to the impressed audience, who cheered her on.

The mother and daughter shared a tight hug on stage after their duet as Pink doted on the youngster.

Fans took to social media to praise the 'talented' Willow, who previously performed on stage with Pink on the very first night of her Summer Carnival tour in June.

One gushed: 'Willow you are so talented. I'm a fan!'

“She's so effortless. Always such great work. Her parents have every reason to be just as proud of both their babies,” another added.

Someone said: 'Proud mum, Willow has a beautiful voice and everyone in the audience loved this duet tonight. Great show as always.'

“I love how Alecia looks at her daughter Willow! Such a proud, loving mama bear;” “She's so effortless.”

Elsewhere during the show, Pink also brought along her son Jameson for his stage debut in an adorable moment.

The youngster was briefly seen running onto the stage after Pink was given a chocolate bar, but sweetly decided to hand it to her son.

Jameson jogged outside to greet his mother and waved briefly to the crowd before heading back into the crowd to rejoin his family.

As the crowd cheered, Pink said, “He got my shyness!”

“I had one chance to eat a whole piece of candy and gave it to my child,” she added jokingly.

Pink had a very eventful first night of her Australian tour, as she also had to stop the concert briefly when a fan went into labor.

After seeing a pregnant woman being wheeled out of her concert by a doctor, the So What hitmaker paused midway through her performance of Our Song to see what was going on.

When she discovered the concertgoer was having contractions, the mother of two excitedly tried to find out the baby's gender.

'Is it Alicia or Alex who is born? she asked, referring to her own birth name, from the stage.

Pink, who admitted she didn't feel like they had to “watch” anymore, urged the crowd to give the woman some “privacy.”

'Wow, Our Song, that was the one that did it. I wouldn't have called them! “I thought it was going to be Get The Party Started or “Never Not Gonna Dance Again,” she said.

'That is exciting. I don't even know what to say. But we have to sing now. Good luck! It will be great! You're going to do great,” she shouted.

This isn't the first time a fan has gone into labor at one of her shows, as in August, a fan named Angela Mercer went into labor during her concert at Fenway Park in Boston, Massachusetts, and later welcomed a son.

After the first night of her Australian tour, Pink took to Instagram to share a gallery of photos from the concert and show off her favorite moments.

She shared a series of photos and videos of herself flying over the crowd in a harness in one of her famous death-defying stunts, despite the fact that it was raining heavily and she refused to be deterred.

Pink also posted two photos of her husband Carey and their children Willow and Jameson, fast asleep backstage as they all rested after the packed show.

In the caption she wrote: 'Sydney!!!!!! That was a wet one!!!!! Rain or shine, we're here.

'We helped bring a baby into the world, we found a new favorite candy bar. Jamo made his debut and I outlived my entire family.

'The crowd also flashed on the way back to the dressing room. Accidentally. I think. I'm so happy to be here!!!!!'

The global star will travel the country for a series of shows on her Australian tour before ending in Queensland on March 23.

Pink was born and raised in the United States but has become an 'honorary Australia' after breaking records for concert and album sales Down Under.

According to a report in New idea Pink hopes to start a 'new chapter' in Australia with her family last year and is considering setting up a 'base' Down Under.

She has long considered Australia a second home and said she was “exploring” possible citizenship in February 2023.

“Australia will be such a special time. Setting up their long-awaited dream base Down Under, where they can escape the winter months, is just what the doctor ordered,” said an insider.

“Last year I was thinking about applying for citizenship, I'm not even kidding,” she said on 60 Minutes.

Pink added that she told her husband Carey Hart that they had to move with their children Willow, 12, and Jameson, seven.

“I was like, if we're going somewhere, Carey, that's where we're going. So I was kind of looking for it,” she added.
