It's a very sad day for Kelsea Ballerini. After a years-long cancer battle, her beloved dog Dibs has passed away. The singer-songwriter shared the devastating news with her fans via Instagram on Thursday, writing: "my sweet dibs went to doggy heaven yesterday. he spent his last few days in his backyard looking at the sunshine and surrounded and visited by his forever people. there are no words to articulate his role in my life, but i couldn't have done the last ten years without him, and he will always be my soul dog...and i pray and believe we'll find each other in every life.
