Jillian Michaels: 'Biggest Loser' Trainer Still Kicking Butt

jillian michaels is back on biggest loser

Motherhood has definitely NOT transformed the over-the-top vocal approach utilized by returning 'Biggest Loser' trainer Jillian Michaels.

During the first of a two-night premiere of the popular NBC weight loss series dubbed Challenge America, Michaels severely browbeat two of the men on her team of five and managed to totally break the spirit of one woman-- who fled for home and therapy before the first weight-in.

Jillian took two years off the show to adopt a Haitian-born daughter Lukensia, 2, and to support her partner Heidi Rhoades, who delivered their son Phoenix 8 months ago.

Now she's back and she appears to be harboring a great deal of pent up hostility that she makes no attempt to hide.  Her male counterparts Bob Harper and Dolvette Quince did a great deal of eye rolling last night as they witnessed her barking like a drill sergeant at her flock of shell shocked newbies.

Raising a family has apparently had zero impact on the way she will approach her training tasks on season 14 at 'The Biggest Loser' ranch.  "Everybody was like, 'You're going to be so much softer.'  And I really want to be, but it's not the case."

Hang on to your hats.  It is likely to be a rocky ride.
