In pictures: Grumpy Cat has gone on a tour of London's landmarks

Remember Grumpy Cat? It's pretty hard to forget that weird little face, but in case you have, let us refresh your memory:

The internet's most famous cat shot to feline fame back in 2012 after a picture on Reddit of her not-so-smiley expression went viral. And now Grumpy Cat, who also goes by the name 'Tardar Sauce', has taken the trip over from the US to go on a whistlestop tour of London's landmarks. Because why the heck not? She's been to Big Ben, Westminster Abbey and even taken an obligatory snap on the zebra crossing by Abbey Road Studios. 

Check out her sassy holiday snaps:
