Faith Hill and her daughters  went shopping in London on Friday. Faith, Maggie, Audrey, and Gracie all stopped by TopShop , Next, and Urban Outfitters  and left with bags in hand. The girls were without Tim McGraw  for their latest UK outing, though he did join them for a walk around the city after landing at Heathrow Thursday. Yesterday, Tim was busy doing press for the Country to Country festival, which takes place this weekend at London's O2 arena. He's one of the many country performers, including Carrie Underwood , Little Big Town, and LeAnn Rimes, who will take the stage tomorrow and Sunday for the first annual event. Tim will be singing tracks from his latest album, Two Lanes of Freedom, and tweeted that it'll be his "first time to play the new album this far from home!"
