The 16-year-old musician, who is coming out with a nail polish line, played two sold-out concerts while in the state capital of Honolulu.
The next day, Justin met up with Jasmine V and best bud Jaden Smith for a boat ride on a catamaran called Mai Tai.
Justin tweeted, “Hawaii lets spend some more time together. Sick day out on the boat with the whole crew. Little Jack Johnson playing and some sunshine and some sea turtles and dolphins. Great day.”
