Kristin Cavallari is a mama grizzly!
The Hills star was spotted in Hollywood on Thursday leaving a photo shoot carrying baby Camden.
In his car seat.
We guess all that working out post-baby has really put the new mom in shape! She's looking as tiny as ever but is power lifting like a champ!
We just hope she isn't putting NFL hubby Jay Cutler to shame!
