We may have seen pretty much all of her body, but it's not often we get to see Kim Kardashian's funny side.

However, a new advert she's filmed with T-Mobile for the Super Bowl has given us a glimpse at Kim's comic abilities – and we've got to admit, we're pleasantly surprised at her line in self-mockery.

Filmed in the style of a charity appeal, Kim K makes a plea with the viewers to not waste their precious mobile data – precious mobile data that could be used to see more of her selfies.

Each month millions of gigs of unused data are taken back by wireless companies. Tragic,' Kim says over mournful piano music. 'Data you paid for that could be used to see my makeup, my backhand, my outfits, my vacations and my outfits. Sadly all lost. Please, help save the data.'

And don't forget – if you do heed Kim's advice and end up using all your data looking at pictures of her, then fear not: You can always pick up her new selfie-themed book, Selfish, and be safe in the knowledge that you've always got a hard copy of Kim's pictures by your side...
