Over the past few months, Mariah Carey
has been shedding her baby weight with ocean workouts
and walks with her dogs
– and even though she's looking quite slim these days, her furry fitness trainers aren't cutting her any slack!
On Friday, a very svelte looking Carey Tweeted
a photo of herself burning some more calories with her barking brood.
"And They Call It Puppy Love," she wrote. "Me & dem pups at it again!"
Sounds like the singer's five Jack Russell terriers – Cha Cha, Jackie Lambchops, Jill E. Beans, Squeak E. Beans and JJ – aren't afraid to give their megastar Mom a little tough love during a workout!
