Miley tweeted "woke up to sloppy wet kisses from the cutest boy on the planet!!! Guess who?" and included an adorable pic of herself and her dog Happy sharing a smooch.
In the shot, Miley, 19, shows off some some spectacular bedhead. Her newly platinum, sheared tresses stand straight up as she kisses her Rottweiler-Beagle mix.
Miley rescued Happy back in May after someone abandoned the pup in front of a Walmart. Since then, he's been living the life with Miley, Liam and their menagerie of dogs.
Any dog would be lucky to join the Cyrus-Hemsworth fam!
