Justin Theroux steals the show at Zoolander 2 - before posing with wife Jennifer Aniston

Justin Theroux was unrecognisable as he arrived for the Zoolander 2 world premiere in New York City this week. The 44-year-old actor delighted fans by walking the purple carpet in character as the movie's 'Evil DJ', his face transformed with mismatched eyes, a three-pronged beard, a scar and long dreadlocks.

He completed his look with a NY Yankees hoodie, tight white trousers, a baseball cap and distinctive gold winged hightops.

Thankfully Justin was back to his usual handsome self as he posed for pictures with his wife Jennifer Aniston. The couple were the style standouts at the premiere, with Jennifer, who will celebrate her 47th birthday on Thursday, looking stunning in a ribbed crepe Galvan dress that featured a hidden corset and a thigh-high split. Her husband, who is the sequel's screenwriter, was dapper in a black suit, white shirt and black tie.

Jennifer was no doubt a big fan of Justin's decision to dress up for the premiere. Justin has previously spoken about his wife's witty sense of humour, describing their marriage as "a laugh a minute".

"When we get on a run, it is pretty fun," he told Loaded magazine. "There's been a couple of times when she has brought me to my knees laughing, and me her."

Zoolander 2 hits cinemas on Friday, just in time for Valentine's Day weekend. And while fans will likely flock to see the long-awaited comedy, Justin said he has got some pretty big plans in store for his wife.

"We're probably going to have a romantic date night," he told Entertainment Tonight. "Her birthday falls like three days before that so I'm just wearing out my credit card on her birthday and then that."
