It's incredible that such a big star (with 9.5m Instagram followers) can take the time to reply to her fans personally like this. Lesson learnt here: never be too big and distant for your own good!

Social networking has given celebrities and businesses alike the chance for followers and customers to really get close to them and genuinely engage - and this is an opportunity that shouldn't be wasted. Taylor Swift's messages are humourous and authentic, and must be a joyous experience for the starstruck fan on the receiving end. Well done Taylor - I bet your PR manager is loving you for this!
