Justin Bieber and Selena Gomez Hold Hands, Hit the Beach in Maui

The Justin Bieber-Selena Gomez cuteness continues! The Bieb and his lady love sealed their relationship with a kiss in front of the cameras at the Billboard Music Awards Sunday night, then they were spotted holding hands while on vacation in Maui Monday! 

The teen couple was seen walking down to the beach yesterday -- and a shirtless Bieber even carried his gal's towel as they made their way to the water. What a gentleman.

Selena looked great in cutoff denim shorts with a fuchsia bikini top and did her part by carrying an adorable leopard print beach bag.

So, what's the occasion? Well, considering Justin was out of the country for months and months on his tour, we're guessing he owed his girlfriend some quality time together -- read "a totally awesome island getaway."
