Newly-hitched Pippa Middleton and her hubby James Matthews have touched down in paradise for their extravagant honeymoon and X17 has the exclusive pix of the just-married couple as they transferred flights during a layover in LA.

Pippa, 32, wed her financier boyfriend, 41, in a traditional English country wedding near the Middletons' estate. Duchess Kate and Prince William were in attendance, of course, as were their children George and Charlotte. And as their magical day came to a close, they slept just a few hours and then hopped a flight for paradise -- French Polynesia.

We spotted the couple as they made their way through security at Los Angeles International Airport -- Pippa looking tired and James, too. The newlyweds will vacation at The Brando, a private island in the French archipelago on a private island called Tetiaroa. The eco-friendly resort is on the island once owned by Marlon Brando and villas go for anywhere between $3,500 - $16,000/night!

No doubt Mr. Matthews will treat his bride to the most expensive 3-bedroom villa for complete privacy. They can fish, snorkel, SCUBA dive, relax at the pool, play tennis or myriad other activities ... or just enjoy their villa :)
