Kristen Stewart and Robert Pattinson arrived back in New York this morning after a romantic getaway in his native England. After spending time in Germany to promote the final installment of Twilight, Breaking Dawn Part 2, the pair flew to London where they spent a few days relaxing after their hectic premiere schedule. An excited fan spotted Rob and Kristen boarding her plane at Heathrow airport, and tweeted, "Look who's on my plane!!! Robert Pattinson and Kristen Stewart!! They have gone up to first class with Paul McCartney!"
