Paris Hilton and her supermodel beau River Viiperi are adventurous lovebirds!

The striking twosome took their love under the sea while scuba diving together. Whether in Hawaii, hitting the fashion shows in New York or hanging in Southern California ... these two seem to have fun wherever they go.

The beautiful blonde heiress is currently in Istanbul, Turkey shooting a campaign and commercial for the clothing company Defacto. For three days of work, Ms. Hilton is taking home $2 million! Not too shabby.

We love seeing Princess P so happy and in love. Who knew snorkeling could be this sexy?
