Can't get enough of the app? Nor can these famous faces...
The internet's gone wild for the face-swapping craze as of late, and celebs are no exception. Face Swap Live was the iPhone app that first got us all excited to morph our mugs with that of our mates last year, then Snapchat got in on the action with a free function which gave way to a new kind of crazy.
So in time-honoured tradition, we've collated the best of what the internet has given us from celeb face swaps.
Kylie Jenner and Blac Chyna

Probably the two most unlikely candidates for our fave app, but nevertheless still as entertaining. Kylie and Blac Chyna shocked fans once again with their unexpected Face Swap, after a day of hanging out on their Snapchats, and we must admit, it is pretty LOLs.
The Queen and Prince George

Granted, The Queen and Prince George didn't actually grab the nearest smartphone and try the app for themselves, but this may be the next best thing. Jenny from Twitter decided to see what the Queen and Prince George would look like face-swapped and honestly? This may be the best thing we've seen all day. As Jenny wrote, 'Guys, I just faceswapped the Queen and Prince George. #SCREAMING.'
Chrissy Teigen and John Legend

Surely one of the most LOL face swaps we've ever seen, poor old Chrissy shared this gem on social media alongside the caption: 'I'm going to vomit'. The pair are getting ready to welcome their first child and are clearly having a lot of fun waiting it out - but it's probs best they don't show this pic to their little one, right? Vanessa Hudgens and Selena Gomez
The internet basically blew up this week when Selena and Vanessa released this video of their morphed faces - Vanessa's on the left by the way (...yeah, we couldn't tell either!)
Kim Kardashian and Kylie Jenner

It should probably come as little surprise that sisters Kylie Jenner and Kim Kardashian bare more than a passing resemblance to one another - y'know, given that their sisters and all - and sharing this Snapchat face swap last year, they looked almost identical. 'I've always wanted to look like you' Kylie said in the video before the sisters fell into a fit of giggles.
Louis Tomlinson and Liam Payne
The Brit Awards 2016 was a night of epic face-swapping on the red carpet, with Louis and Liam proving why some people might still get them mixed up - in fact, it's freaky how their faces seem to be a perfect fit for each other. Winning!
Scott Disick and Kourtney Kardashian

Sometimes celebrity face swaps can be truly nightmare-inducing - and this is defs one of those times. This cartoonish Snapchat between the friendly exes was debuted to the world just last month (to the sound of muffled screams probably).
Ariana Grande and Alan Carr
Quite possibly the most random celebrity face swap of the lot, Ariana Grande traded features with Alan Carr when she was a guest on his show earlier this year.
Harry Potter and Matt Lucas
Ok, so Daniel Radcliffe wasn't actually complicit in this one, but it doesn't make it any less funny. Matt was (probably) really bored when he decided to super-impose Daniel's face onto his own back in February with one of the super-dooper Snapchat filters and uploaded a series of videos of him doing his best (90-year-old) Harry Potter impression - LOLs.
Marvin and Rochelle Humes

We love a good celeb couple face swap and this one between Rochelle and Marvin Humes is absolutely gold.
Happy face swapping, folks!
