In particular, Justin Bieber and his six-year-old brother Jaxon stole our hearts. Donning matching black-and-white suits and similar hairstyles, the two showed off their brotherly love on the red carpet.
Not only did Bieber adorably tickle his mini-me in front of photographers, but he also planted a smooch on his baby bro.
The 21-year-old pop star previously proclaimed on social media that he loves being a big brother, so it’s no surprise that he would bring Jaxon as his Grammy date.
The brothers have also been spending a lot of time together these past few months. In January, they were spotted vacationing in the tropics together with their dad Jeremy.
But while Bieber and his little brother certainly stole our hearts at the Grammy awards, they weren’t the only ones! Flip through the slideshow below to see all the adorable celebrity kids who walked the red carpet.
