Ashley Greene & Vanessa Hudgens -- It's Tiny Bikini Time in Bali

The sun wasn't the only thing that was hot in Bali yesterday -- Ashley Greene and Vanessa Hudgens went two pieces on the Indonesian island.

The actresses sunned themselves in barely-there bikinis while attending the Oakley Pro Bali surf competition. Ashley even took some surf lessons herself.

We'd say more ... but a picture is worth a thousand words.
