The expecting star took to Instagram to share a series of new snapshots to give her fans an update on her growing baby bump.
In one pic, the former "Hills" star, who's rocking a black sweater and gray shorts, puts her belly on full display as she teases her two dogs with treats.
"Their begging skills are on point," she captioned the cute candid with her furry friends.
Another photo shows the petite blonde in the gym, performing a squat with weights in both hands and her baby bump in tow.
Judging by these latest pics, it looks like she's found the secret to a fit pregnancy!
Cavallari revealed that she is expecting her third child -- a baby girl -- with NFL hubby Jay Cutler back in May. The couple already has a house full of boys with sons Camden Jack, 2, and Jaxon Wyatt, 1.
