Katy Perry has got her hands on a brand new snuggie and it's possibly the greatest thing we've ever seen!

We all know what a snuggie is and you can even get couple ones, but we've not seen one with a pattern or design on it...until now!

Katy Perry showed off her Oscar the Grouch (from Sesame Street) snuggie on her Twitter account and we couldn't be more jealous.

Not only cosy but totally awesome too! Think we would like a Cookie Monster one though, since all we'd be doing in it is eating biscuits in front of the TV...

Katy likes to experiment with clothes!
