AceShowbiz - For TikTok sensation Chris Olsen, his 27th birthday was a star-studded affair. The influencer kicked off his special day early by attending Billie Eilish's Los Angeles concert on "birthday eve." Surrounded by pals, Olsen enjoyed Eilish's performance of her hit "Wildflower" and a rendition of "O Holy Night."

On his actual birthday, Olsen reunited with his best friend, Meghan Trainor, for a joint celebration. The duo rented out a rage room, where they channeled their energy into hitting a car. While their initial attempt was underwhelming, they eventually made a significant dent.

In addition to the rage room adventure, Olsen and Trainor shared a festive photo shoot to commemorate their shared birthday.

Olsen's birthday celebration comes after a challenging year. In an interview, he revealed the hardships he faced alongside the highlights of joining Trainor on her "Timeless Tour". However, Olsen has since found solace in reconnecting with himself and focusing on activities that bring him joy.

As one of PEOPLE's 2024 Creators of the Year, Olsen has found success in sharing comedy content with his followers. He believes that what makes him happy also resonates with his viewers. "Touching back in with myself is what helped," he said. "And it continues to help."
