Angelina Jolie and Brad Pitt are not married, says Taraji Henson - despite outing the couple as husband and wife on the red carpet recently.

The actress - who stars alongside Brad in The Curious Case Of Benjamin Button - referred to Brad as Angelina's "husband" not once, but twice during a brief interview.

But Taraji insists it was merely a mistake derived from the fact Brad and Angelina live together with their six children.

"It was a slip," she tells E!.

"I mean, they have a family, they live together. What is married really? It's like they are married."

If Taraji is in the dog house with Hollywood's hottest couple at all, she's found the perfect way to make amends.

She says, "I told Angelina, 'I will babysit for you anytime,' 

"All the kids are very adorable. They're good, good kids."
