Jennifer Aniston & Justin Theroux Enjoy Hawaiian Quality Time, Celebrate Christine Taylor's Birthday

Jennifer Aniston and boyfriend Justin Theroux flew to Kauai, Hawaii, on Sunday for a little quality time and the new couple seems to be making the most of the island paradise.

On Monday evening the “Wanderlust” co-stars headed to an oceanfront villa to help Ben Stiller and wife Christine Taylor celebrate Christine’s 40th birthday, according to People, but first stopped off at the Lotus Gallery of Fine Art to grab a gift.

“They seemed to have a great time,” an eyewitness told the mag of Jen and Justin’s gallery visit.

“They were the only people in the store and seemed extremely relaxed and happy,” a source told Us Weekly. “Jennifer was hugging Justin from behind.”

The pair settled on a small statue of Buddha, Us Weekly reported, before sharing a smooch at the register while the clerk wrapped the gift.

“When they left the store, Jennifer was massaging Justin’s shoulders from behind, and he turned around and said something that made her laugh hysterically,” the source told the mag. “They seemed giddy in love and genuinely happy together.”

On Tuesday, the couple went sightseeing and later stopped at Banana Joe’s Fruit Stand for a sweet treat, according to People.

“They are acting like regular tourists,” a source told People. “They have been touring the island in a rented Jeep … Justin is beyond sweet and attentive to her.”

As previously reported on AccessHollywood.com, Jennifer and Justin are reportedly moving in together after less than three months of dating.

Jennifer, 42 recently sold her Beverly Hills home for a whopping $38 million and must vacate her old digs by the end of the month, according to People.

The happy couple recently embarked on a house hunt in the Los Angeles area, the mag reported, but has yet to find a new home.
