Jennifer Aniston & Justin Theroux jet off on a Hawaiian holiday

Jennifer Aniston and her boyfriend Justin Theroux have been enjoying a relaxing getaway on Kauai, Hawaii, since July 31.
The couple who are planning to move in together reportedly spent Monday helping Ben Stiller and his wifeChristine Taylor celebrate Christine’s 40th birthday at an oceanfront villa. Before attending the birthday party, the couple stopped by the Lotus Gallery of Fine Art to pick up a gift.
“They seemed to have a great time,” an eyewitness told People magazine.
Aniston and Theroux went sightseeing across the island Tuesday and made a stop for tropical juice and fruit at Banana Joe’s Fruit Stand.
“They are acting like regular tourists,” says a source. “They have been touring the island in a rented Jeep … Justin is beyond sweet and attentive to her.
“They have been jogging by their villa and they are both in great shape.”
