Brad Pitt is "longing for" sleep following the birth of his twins in July. The 'Burn After Reading' star - whose babies Knox Leon and Vivienne Marcheline are his fifth and sixth children with partner Angelina Jolie - admitted while he is happy with the new additions to his family, he wishes he could spend more time in bed.

Asked how the twins were doing, Brad replied: "They are all good - everyone's healthy, and everyone's great.

Sleep is something we long for, but that's alright, we'll get it soon!" When the 44-year-old actor was questioned about what makes him laugh, he replied: "My kids!"

Brad appears alongside close friend George Clooney in 'Burn After Reading'. In the movie, from legendary directors the Coen brothers, Brad plays Chad Feldheimer - a gym employee who finds a disc full of personal financial files and uses it to blackmail Osbourne Cox, played by John Malkovich.

The film is released worldwide later this year.
