Gwyneth Paltrow has refused the opportunity to congratulate former fiancée Brad Pitt on the news he is to become a second-time father.

Paltrow and Pitt began dating after they met on the set of their 1995 film Se7en and were even engaged to be married before they parted ways in 1997.

And although it has been more than ten years since the pair split, Paltrow appeared less than happy to be questioned about her ex at the Los Angeles premiere of her newest film Iron Man.

When asked if she had any well wishes to share with Pitt, whose partner Angelina Jolie is pregnant with the couple's second child, the Shakespeare In Love star declared: "No!"
