Happy birthday, Justin TherouxThe Hollywood star turns 46 today, and what a year it has been. After saying, “I do,” to his fiancée of three years, Jennifer Aniston, last August, the actor landed one of his biggest acting roles yet, as Tom Watson in the book-turned-movie thriller, The Girl on the Train, which hit theaters on Oct. 7.

Luckily, the big screen isn't the only place we can catch Theroux in action: The actor and director shows off his epic love affair with Aniston, looking picture-perfect together on red carpet and cozying up on the streets of N.Y.C. Long before the couple started dating, they were friends, and that friendship has evolved into true love.

The lovebirds embraced each other as they posed for photographers at an Oscars after-party.
