The couple, who got married during a surprise ceremony in front of approximately 75 guests at their mansion in Bel Air, California earlier this month, reportedly spent lots of time alone during their celebratory trip to Bora Bora despite jetting there with several close friends, including Courteney Cox, Jimmy Kimmel and Jason Bateman.

The newlyweds were spotted taking a romantic strolls along the beach and an eyewitness told PEOPLE magazine: "They looked very happy. They had their arms wrapped around each other and were in their own world. They looked blissful."

They also enjoyed several couples spa treatments together.

But the duo still spent plenty of time with their friends and organised group beachside yoga sessions, as well as water-sports to keep everyone entertained.

Justin, 44, arrived back in Los Angeles with the 'Cake' actress, 46, over the weekend and was spotted jetting out of Los Angeles International Airport on Monday (17.08.15) to resume filming 'The Leftovers' in Austin, Texas.

It was previously revealed that the former 'Friends' star pretended she and Justin had gone on holiday so they could quietly plan their backyard wedding.

An insider recently said: "They were actually home, furiously wedding planning. Jennifer even confiscated all staffers' phones so nobody could take pictures."
