Justin Theroux Calls Himself the "Luckiest Guy" in the World

It looks like Justin Theroux and Jennifer Aniston's relationship is only going stronger over time. As happy as they are in photos, the couple admits to being as happy in real life.

The 40-year-old actor admitted on Extra that he could not be happier right now in his life, with regards to his relationship with Jennifer Aniston. In fact, Theroux referred to himself as the "luckiest guy in the world" to be the one who's with Jen.

Jennifer and Justin made their relationship public last year in April. Although there were controversies at the beginning, they have managed to overcome them all and are now happily in the arms of each other. The pair was spotted catching a flight to Paris, France over the weekend.

"They were hugging and kissing as much as possible," says an onlooker who was at the airport.

"They got airline priority to get through customs and security, but were in no hurry. They were just so happy to be together and starting a visit to Paris as a couple."

The Rock of Ages co-writer and Aniston got together in the movie "Wanderlust" and from then on developed their budding romance. Last May on the issue of Marie Claire Australia, the 43-year-old actress reveled what she loves most about her boyfriend.

"He's a protector, for sure," she said. "He's just a good human being, and so funny."

According to friends close to the actress, Aniston's relationship to Theroux is completely different from Brad Pitt, Vince Vaughn or John Mayer. They said that the two seems like a perfect match.

"Their relationship is completely different than any of her other ones," a friend of Jen told US magazine. "Everything about Justin feels right."
