Now that they've gone 100% public with their relationship, Justin Bieber and Selena Gomez can't keep their hands (or lips) off each other!
The two were seen having numerous public displays of affection yesterday while vacationing together in Maui -- taking time to kiss while jet-skiing, swimming and parasailing!
The young couple are on the trip with a chaperone -- Justin's mom!
Selena, 18, and Justin, 17, made their first public smooch Sunday night at the Billboard Music Awards.
