Paris Hilton, 31, has been dating hot Spanish and Finnish model, River Viiperi, since September, and the two proved that they are just as hot and heavy as always when they hit the pool in Miami this weekend.

Hilton wore a one-piece, one-shoulder bathing suit and Viiperi wore a matching zip-up hoodie, which he soon removed to soak up the sun shirtless and cozy up to his famous heiress girlfriend in the water. The lovebirds also both sported black hats and oversized sunglasses.

When a fan commented on their matching looks on Twitter, Hilton tweeted "#Twins" along with a winking face. Viiperi also tweeted about his delight to share the weekend with Hilton. "Day 2 by the pool with my gorgeous Blonde @ParisHilton #LifeisPerfect."
