Before he was singing about that "yummy-yum," a young Justin Bieber was serenading new fans with "Baby," his debut album's lead single that was released on Jan. 18, 2010.
Exactly a decade later, Bieber reminisced about those early days of his career on social media, where he marked the song's 10th anniversary with a quick nostalgic post.
The pop star simply wrote "10 years," along with the eyes emoji, as a caption.
His mom, Pattie Mallette, replied with a crying emoji.
Longtime manager Scooter Braun left a comment, too, writing: "It’s been an amazing 10 years. Here is to the next 10!"
Check out Bieber's throwback to the "Baby" artwork, plus the track's original music video, below.
