The diva has previously spoiled her dogs--Jack Jr., Cha-Cha, Dolomite and Jackie Lambchops--with lavish accommodations, touting them along with her to video shoots and press appearances. After getting married in 2009, her husband Nick Cannon gifted her with Cha-Cha, making it her second dog after JJ. Cha-Cha later birthed Dolomite, while Jackie joined the clan in June 2010.
Aside from worrying about their pets' mental sanity, Mariah and Nick are currently prepping for the birth of their twins, a first for both. The two revealed that they are expecting a boy and girl, a secret that they kept until last month.
"Even before we announced it was twins, I was trying to keep everything gender-neutral because I didn't want to impose an identity on them too soon," she said at the time. "There were fan contests on Twitter about what gender they are and rumors about them being two boys or two girls -- but nobody guessed this!"
