Rossdale echoed similar sentiments in a tribute of his own, which was shared with a slideshow of images of Kingston.

\"HAPPY BIRTHDAY KINGSTON - 18 today and a massive step into your future,\" he wrote. \"so far the best ride of my life and i can't wait to see where you go from here. i have total belief in you and deeply admire the man within. you have grace, charm and humility.\"

\"you are at the wheel of your destiny so choose wisely. your musical talent is nuts and soon the world will hear your heart sing,\" the Bush frontman continued. \"follow your muse, stay curious and keep creating. i could not love you more than i do. i wish you all the happiness all the health and all the creativity. love you dad. ❤️.\"
