Internet sensation Grumpy Cat visited Abbey Road Studios and Buckingham Palace on a whistle-stop tour of London’s landmarks.

The sullen-faced moggy prowled around city sights including Westminster Abbey and the Houses of Parliament in her “British invasion”.

Outside the Queen’s home, the four-year-old pet – real name Tardar Sauce – showed she was not amused, before proving her meow-sical talents at the recording studios made famous by The Beatles.

The US cat's visit was part of a promotional tour for a new Primark clothing range.

The tour comes ahead of a “signing” at the Oxford Street HMV on Friday, where British cat-lovers will get a chance to meet the feline celebrity.

According to her owners, Grumpy Cat's unique facial expression - which has spawned countless internet memes - is the product of a feline form of dwarfism which gives the moggy an underbite.
