Kim Kardashian and Demi Lovato blow us a kiss to celebrate Demi's birthday!

If you didn't spend yesterday baking dozens of cupcakes and eating them all in one sitting while listening to "Skyscraper" on repeat in honor of Demi Lovato's 20th birthday (just us?), you can properly redeem yourself by awww-ing at this adorable photo that Kim Kardashian tweeted of herself and the "X Factor" judge blowing us invisible kisses.

Kim joined the gazillions of other famous peeps on Twitter to wish the "Give Yourself A Break" singer a very happy 2-0 with the super cute photo along with an equally sweet caption, "Happy 20th Birthday DemDem!!!! I love you @ddlovato." While we can't even handle the beauty that is these two (we can actually hear the fluttering of those flawless, feathery eyelashes), we're more obsessed with how these two look related in this photo! We know we've said it before, but Demi could SERIOUSLY be one of the long-lost Kardashian sisters! Just in case there aren't enough Kardashians already.
