Justin Theroux is an eyeliner addict, according to Page Six. According to an insider the "Zoolander 2" actor has taken to wearing a healthy dose of eyeliner as he's a little high-maintenance over his look.

Justin's wife Jennifer Aniston even advises her husband on the brands that might best flatter his brown eyes, according to the insider. A second source claims that the 44-year-old actor is very particular about his red-carpet look.

Justin likes his clothes to accentuate his slim-yet-muscular physique. The "Wanderlust" actor likes to wear shoes that give him as much height as possible because he is a touch sensitive about his 5-foot-9-inch frame, the second source says.

In a previous interview with The Telegraph, Justin said fashion was "the funniest" thing to do. "In a weird way fashion, which is frivolous to the core, shouldn't be taken seriously, but thank God people do: it makes for great people watching," he explained, "I ride a fine line with fashion between on the one hand really liking going to (runway) shows - which are basically like Cirque du Soleil with no silks or ropes - and at the same time finding some of the people in and around it the funniest on the planet."
