Justin Theroux opens up about 'large manhood' on chat show

London: Justin Theroux joked about his "prominent package" and said that he didn't know it was "a thing" till he was told to wear more than one pair of underpants for a jogging scene in ' The Leftovers'.

During the show, Conan O'Brien quizzed the fiance of Jennifer Aniston about his bulge to which he replied that he didn't realize it till he was asked to wear two pairs of underwear for the second jogging scene in the new TV drama, after his bulge was very prominent in the first, reportedly.

His costar Liv Tyler also admitted that his bulge was distracting as she "couldn't help but look there".

Theroux, who has been dating the former Friends star for the past few years, appeared embarrassed but joked about it on the chat show, when O'Brien congratulated him on his generous package.
