Jennifer Aniston, Justin Theroux Leave Hawaii

 Splash News

Quasi-honeymoon's over!

After two romance-filled weeks in paradise, Jennifer Aniston and Justin Theroux left the luxe Hawaiian island of Kauai on Saturday via private jet, Us Weekly has confirmed.

For the lowkey trip — a hybrid business/pleasure vacation to celebrate Theroux's 40th birthday Aug. 10 and work on a script — the Wanderlust costars rented a $7,000-a-day oceanfront/clifftop estate on the island's North Shore.

Although 42-year-old Aniston and her beau made a couple public appearances — shopping at a local gallery, grabbing coffee and a roadside coconut — their trip was mostly a quiet, intimate one. The couple indulged in daily yoga, oceanfront jog, massages and bike trips around the estate.

"She's detoxifying," one source tells Us.

One thing on their R&R agenda: Getting pregnant!

"They have talked at length about getting married and starting a family," another pal says. "She is anxious for the next phase of her life and feels like this is the time."

Now that they're back in L.A., it's time to house hunt! "Justin plans to live with Jennifer," a source says. (Aniston recently sold her Beverly Hills home and snatched up two apartments in NYC near her man.) "The house is definitely something they are deciding on together."
