Last summer, Jennifer Aniston and Justin Theroux shocked the world (and even their friends) when they threw a surprise wedding at their home, inviting their closest people for what seemed to be a birthday party and ended up seeing the two lovebirds becoming husband and wife - but just a few days later, during Jennifer Aniston's honeymoon, the "Friends" star almost became a widow.

As it has been already reported at length that Jennifer Aniston's honeymoon was in Bora Bora, where the two spent a few days enjoying their newlywed status on the tropical paradise, even enjoying scuba diving - which also resulted in Theroux's death.

According to The Daily Mail, the star of HBO's "The Leftovers" was recently on "Live with Kelly and Michael" to talk about his show and his life with Aniston as a newlywed, and he shared something nobody had heard about Jennifer Aniston's honeymoon: while he was scuba diving, at some point he was deep underwater with no oxygen, near death.

Us Weekly reports that, while scuba diving deep in the ocean during Jennifer Aniston's honeymoon, Theroux noticed his oxygen tank was in the red and signaled his instructor about it, who completely ignored him and just told him to "keep swimming," and of course, only a few moments later, the actor and screenwriter was pretty lacking in air.

"He just kept swimming away from me," Theroux said. "I got to my friend [and said], 'Dude, look.' And he said, 'Oh my God, you are about to die," shared the star, explaining that the instructor then took out an emergency respirator and they went up to the surface, though it was obviously a pretty scary experience.

According to Page Six, aside from the groom's near-death experience, Jennifer Aniston's honeymoon was actually an amazing affair, as the newlyweds took to Bora Bora's Four Seasons in a lavish affair that included some of their closest pals like Courteney Cox and Chelsea Handler, with the whole thing going up about $50,000.
