The Hill-McGraw family had their cameras ready for an afternoon of sightseeing in London yesterday. The group, including Tim McGraw , Faith Hill , and their daughters, Maggie, Gracie, and Audrey, toured Windsor Castle before heading to a pub for lunch. The group has been in the UK since last week and took to the streets immediately after touching down at Heathrow on Thursday. Tim missed out on a girls' shopping trip the next day, since he was busy promoting his weekend performance at the Country to Country festival. It was his first time performing in London, and he got rave reviews for his set. The family was back together on Sunday, though, when they met up with Chris Martin, Apple, and Moses for a park playdate .
