Justin Theroux’s lady makes him happy. So it’s nice to hear that happiness isn’t tempered by the built-in challenges of being in a super-high-profile relationship. The star of HBO’s The Leftovers said about being with Jennifer Aniston in the August issue of Details, “It doesn’t feel like a hardship. It doesn’t feel difficult.” As for the written words that tend to accompany all those paparazzi pictures in the tabloids, Jen’s 42-year-old fiancé said that “it’s always based on fiction.” But he and Aniston soldier on. And from our perspective, being with Theroux doesn’t look like such a tough proposition either, at least based solely on his ripped physique. The 42-year-old showed off the results of all that time he spends in the gym for Details as well, cutting an impressive shirtless figure, his six-pack abs and muscled arms rippling for the camera.
