Tom Cruise and Katie looked super-cute in a summery crocheted baby-blue dress from the spring 2011 Ralph Lauren Collection, which she teamed with an S (for Suri) pendant necklace and strappy nude platforms.
The actress must have breathed a sigh of relief after her new show, in which she stars as Jackie Kennedy alongside Greg Kinnear, was dropped by the History Channel.
The eight-part series has now been picked up by ReelzChannel, and our very own BBC 2.
Katie says of the show: 'It's been really fun! Her clothes were magnificent. I feel so lucky. We have these wonderful seamstresses who are creating beautiful dresses that are obviously replicas of real things she wore. Armani made two dresses for me to wear.'
Sounds terrible! What do you think of her red carpet look? Leave a comment below...
