Hailey Bieber defended as fans spot detail during Justin Bieber’s Billie Eilish ‘One Less Lonely Girl’ moment

Over the weekend, Billie Eilish got to do what many teen girls in the 2010s dreamed of - be Justin Bieber's 'One Less Lonely Girl'.

Now, hardcore fans of the Canadian singer, 32, will know that when he performed the song in his younger years, he would invite one fan on stage to be his 'lonely girl' during the performance, sing to her, and give her flowers.

And he decided to bring the sweet concept back for his second Coachella headline performance on Saturday (18 April), bringing none other than Billie Eilish up onto the stage.

The 24-year-old singer, who has famously been a huge Belieber since she was a teenager, joined the 'YUKON' hitmaker during the throwback segment of his performance.

In the now viral moment, Billie can be seen dancing in the crowd in front of the festival's VIP box with Justin's wife, Hailey Bieber, 29, who appeared to encourage her to go up.

Seemingly unable to believe what was happening, Billie laughed and covered her face in shock as she made her way over to the singer, hilariously dropping to the ground in disbelief a few times on the way up.

She sat on a stool on stage as Bieber sang the 2009 anthem to her and hugged her from behind, falling to the ground again when the song ended.

The adorable moment has quickly made its way around the internet, with fans wanting to know every little detail of how it came about.

At first, some fans were confused as to why Billie was the 'One Less Lonely Girl,' instead of Hailey.

One X user penned: "The fact that he brought out Billie Eilish for one less lonely girl and not his wife."

However, more videos from the night appeared to show Hailey encouraging the 24-year-old to go up and even excitedly giving her a little push through the barrier.

Fans have been praising the Rhode founder for giving Billie her moment, with one writing on social media: "Hailey is a real one for pushing her to the stage."

A second gushed: "Ohh, Hailey, the woman that you are. She really saw Billie’s moment and pushed her to meet Justin Bieber on stage. That was so special. She made her dream come true."

While a third joked: "Hailey, mother of the Beliebers for real."

Someone else said: "They made her childhood dream come true. Billie will never forget this."

As for how the heartwarming moment came about, some fans have theorised that Justin and Hailey could have pre-planned it as a surprise for Billie, while others are claiming that even Justin didn't know she was coming up on stage.

Once a Belieber, always a Belieber

Billie has long been a fan of Justin, with a clip of her - reportedly aged 12 - talking about her 'love' for him recently resurfacing.

“So many Justin Bieber things. I was like crying so hard because I’ve got worried that when I get a boyfriend, I won’t want to be with him because I actually love Justin Bieber more. And I can’t handle that,” she said.

The pair actually met for the first time during Ariana Grande's performance at Coachella 2019 and a video of the heartwarming moment quickly went viral. From there, they collaborated on a remix of Billie's iconic hit 'bad guy' and went on to build a friendship.

In 2020, Billie shared a pic of herself as a teen, wearing a ‘Justin Bieber’ top. She also posted some snaps of her bedroom, with the walls covered in posters of the ‘Baby’ singer and a sign on her door that said: “Forever Belieber, Billie’s room.”

Appearing in Justin’s YouTube Seasons docuseries that same year, Billie admitted: “I care about him more than anybody in my life.”
