Angelina Jolie made her first public appearance since giving birth to twins in July at the New York premiere of her new film Changeling over the weekend. The Oscar-winner says caring for six children has pumped the brakes on her sex life with Brad Pitt.

The birth of Knox and Vivienne has left the couple “exhausted,” Angelina says.

“We often try and have a bath alone together at the end of the night and sit and talk, but they hear the water and want to jump in. Even if we lock our door, the children come knocking.”

When quizzed on her plans to marry Pitt she replied: “You’ll have to ask Brad.”
