Jillian Michaels is fit, fab and friggin' gorgeous!
She's also a mama!!
She's got her two kids, Lukensia, the toddler she adopted from Haiti and Phoenix, the baby boy born to her partner Heidi Rhoades.
They're one big happy family!
Jillian is learning what it really means to be a mom, and shared it with Jay.
Even all the gross details of what a mother would do for her children when they need some help.
Check out the video (above) to hear how Jillian feels about being a mama!
