Hailey Bieber comforts Kylie Jenner during emotional moment in LA after release of new song

Kylie Jenner’s 'King Kylie' era is officially back, and this time, it comes with a soundtrack. To mark the release of her debut single 'Fourth Strike,' Kylie stepped out in Los Angeles with her closest circle of friends, revisiting iconic spots from the early 2010s that defined her rise.

Among the stops were Urth Caffe, a longtime fan-favorite and a core location from her Tumblr-era days. While sipping coffee, the moment turned emotional for Kylie, who teared up as she took in the nostalgia.

“Order for a King Kylie,” Jenner joked to her friends while holding her drink, with her crew echoing the title back in unison, cheering her on. The celebration came just one day after the 28-year-old reality star turned beauty mogul dropped her first-ever music collaboration, lending vocals to Terror Jr’s new single.

Titled 'Fourth Strike,' the track is a nod to the group’s earlier hit '3 Strikes,' a song long rumored to have featured Kylie’s voice. This time, it really is her.

“I was soooooo nervous but so grateful,” Kylie wrote on Instagram, sharing a behind-the-scenes look at her time in the studio. “There was a little rumor 10 years ago that I was the one actually singing on 3 strikes! It wasn’t me (wish it was) so I had the idea to come together for Fourth Strike and it would actually be ME FEATURED!”

The track also plays in the campaign visuals for Kylie Cosmetics’ 10th anniversary launch, which brings back several products from her original 'King Kylie' collection, complete with metallic glosses, bold palettes, and her signature lip kits.

Fans of the reality star are sharing their excitement, including her celebrity friends, while some are sharing their support for her new music career. Sofia Coppola's daughter Romy Mars even shared her live reaction to the new track and praised Kylie for her new pop star path.

Meanwhile, online users are criticizing the song, declaring they are "unimpressed." Despite the negative comments, Kylie revealed that she is having fun bringing back 'King Kylie' and documenting everything on Snapchat.
