Brad Pitt 'suffering sleepless nights'

Brad Pitt has revealed that he has struggled to sleep since the arrival of his twins.

The actor's partner Angelina Jolie gave birth to Knox Leon and Vivienne Marcheline, the fifth and sixth children shared by the couple, in July.

Pitt commented that while the family are "all good" and "healthy", sleep is something he and Jolie currently long for.

He was speaking at the Toronto International Film Festival, where he is promoting new film Burn After Reading.
