Happy honeymooners!

Newlyweds Kim Kardashian and Kris Humphries looked relaxed and at ease Thursday in Amalfi, Italy. The duo, who said "I do" in a lavish ceremony in Montecito, Calif., on Saturday, were photographed earlier in the day packing on the PDA at a luxe resort.

Kardashian, 30, and her NBA hubby, 26, flew into Paris on Monday, but shortly after, they were whisked away to Italy. They first touched down in Naples, according to a source, where a limousine was waiting to take them to a yacht.

Reality TV's royal couple are expected to spend a week in the Mediterranean, where they'll be cruising the crystal-clear waters off the island of Capri, with stops in the nearby picturesque towns of Amalfi and Positano. (The coast around Amalfi and Positano has been particularly popular with American VIPs this summer, including Reese Witherspoon and Hilary Swank.)

But Kardashian hasn't forgotten about life in the States! Thursday afternoon she tweeted her well-wishes for those preparing for Hurricane Irene. "I hope everyone on the East Coast is safe!" she said. "I hear the weather is crazy!"
