We finally get why Jennifer Aniston is so hung up on Justin Theroux. The Friends' star's fiancé went jogging on the set of his new HBO pilot, The Leftovers, in New York on Wednesday, and showed us one big reason why Jen fell for him.
Justin wore grey sweats while he jogged during a scene in the TV movie, but while he had his iPod (and even wore a wedding ring, which we assume was for his character and not because he and Jen secretly got married), there's one thing he forgot – his underwear. The 41-year-old pulled a Jon Hamm as he ran down the street.
In case you missed this very important celebrity news, the Mad Men star is the object of much Internet love over his apparent refusal to wear underwear – which has gifted the world with some eye-catching crotch shots.
But then he looked on the bright side: "I guess it's better than being called out for the opposite."
