Brad Pitt and Angelina Jolie can’t agree on names for their unborn twins.

The couple - who are expecting twins in August – are said to be arguing over potential names because Brad doesn’t like Angelina’s suggestions.

Gemini Angelina reportedly wants to name the babies Castor and Pollox after the twins of her birth sign, but Brad has dismissed the suggestion as he doesn’t want a daughter with a name “like a British cuss word”.

Angelina confirmed she was expecting twins in an interview last week after her ‘Kung Fu Panda’ co-star Jack Black let the news slip during an interview at the Cannes Film Festival.

Actor Dustin Hoffman later revealed the babies are due on August 19.

Angelina and Brad already have three adopted children, Maddox, six, Pax, four, and Zahara, three, and a biological daughter, Shiloh, 23 months.
