Water aerobics is just one of the ways Mariah Carey
is shedding those post-baby pounds
this summer – and it looks like she's got a mini motivator in her dog Jill E. Beans!
On Monday, the new mom Tweeted
a photo of one of her five Jack Russell terriers
doing the doggie paddle in a pool.
"Sababa!" she wrote, which loosely translates to "cool" in Hebrew.
Last week, Carey enjoyed a sunny "ocean workout" which had her splashing in the waves
. "It's been a loooong time since I've been in the ocean," she Tweeted.
The mom of twins Moroccan and Monroe, who were born in April, has also been pounding the pavement with her four-legged fleet, which includes dogs Cha Cha, Jackie Lambchops, Squeak E. Beans and JJ.
If Jill E. Beans learns to ride a bike, the pooch could participate in a triathlon!
