Jolie, Pitt 'nearly named child Rex'

Angelina Jolie and Brad Pitt almost named their new baby boy Rex, say reports.

According to the New York Daily News, the couple changed the name to Knox at the last minute.

The pair reportedly ordered a play mat with the name Rex Leon Jolie Pitt embroidered on it.

Jolie gave birth to twins Knox and Vivienne in France last weekend.

Knox was the middle name of Pitt's grandfather, while Vivienne comes from the French version of the ancient Latin name, which means alive.
