Liv Tyler celebrated her big 4-0 in style this weekend. She and her guests - including long-time friends and fellow A-listers, Kate Moss and Sadie Frost โ spent a relaxing weekend in the countryside.
The occasion was a laid-back affair, complete with a bouncy castle, tipis and blissful country walks - worlds away from the parties the girls had in the '90s.
