Demi Lovato, revealed she relies on her Batman and Cinderella for emotional support when she's on tour.

'As a #BeVocalSpeakUp partner, I know that living well means different things to each and every one of us,' she wrote.

I find so much comfort in having my support system nearby while I’m on tour – from friends who travel with me on the road, family who I get to see in different cities and even my dogs Batman and Cinderella.'

Both Demi and Mariah scored free dog walks for life from Wag for their canine companions last year.

'Live, Love, WOOF... Happy #NationalPuppyDay to these two!' she beamed.

Nina Dobrev also wished a 'Happy #NationalPuppyDay to my number one bitch. I mean puppy. Number one puppy. You have my heart babygirl.'

She even tagged the collie — @mrs.maverick — as she has her own Instagram account with 356k followers.
