It’s been 15 years since Justin Bieber stole the hearts of teenage girls worldwide with his debut single, “One Time.” At just 15 years old, Bieber made his music industry debut and began a journey that would lead him to become one of the biggest pop stars of his generation. Now, not only is he celebrating 15 years of fame, but he also turned 30 on March 1 and recently announced that he and his wife, Hailey Bieber, are expecting their first child together.


Bieber’s debut EP, My World, featured “One Time” as its lead single, marking the beginning of what fans affectionately call “Bieber Fever.” The song’s catchy chorus and heartfelt lyrics quickly endeared him to millions. The track opens with the memorable lines: “Ay ay ay ay ay ay ay, let’s go / Me plus you I’mma tell you one time.” It then transitions into the first verse: “When I met you girl my heart went knock knock / Now them butterflies in my stomach won’t stop stop / Even though it’s a struggle love is all we got / So we gon’ keep keep climbing ’til the mountain top.”


The pre-chorus and chorus of “One Time” are particularly unforgettable: “Your world is my world / And my fight is your fight / My breath is your breath / When you’re hurt.”


“Cause girl you’re my one love / My one heart, my one life for sure / Let me tell you one time, girl I love, girl I love you / I’mma tell you one time, girl I love, girl I love you / And I’mma be your number one guy / You’ll be my number one girl, always making time for you / I’mma tell you one time, girl I love, girl I love you.”


The music video for “One Time” has amassed 774 million views and 4.2 million likes on YouTube. It begins with Justin and his best friend Ryan Butler playing video games on the couch. Usher, who mentored Justin from the start, asks him to house-sit, leading to a night of fun and partying. The video also features Justin eyeing a girl, Kristen Rodeheaver, adding a personal touch to the story.

Fans have recently been reminiscing about Bieber’s rise to fame, especially in light of his baby news. One fan commented, “And just like that, this is now 15 years ago.. and he’s married and now expecting a mini Bieber.” Another wrote, “Can’t believe he is going to be a dad, it feels like yesterday when this video came out. I really miss the Bieber fever era from 2009-2012.” A third fan added, “This song would be the beginning of one of the best singers EVER.”

Since his debut in 2009, Justin Bieber has released six studio albums: My World, My World 2.0, Believe, Purpose, Changes, and Justice. He has been nominated for 23 Grammy Awards and has broken records, including having the most-watched video on YouTube with “Baby.”

However, Bieber’s career has not been without its challenges. In January 2014, he was arrested for driving under the influence, driving with an expired license, and resisting arrest “without violence” in Miami, Florida. Despite these setbacks, his fans believe these experiences have helped shape him into the man he is today.
