One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
Stacy Keibler showed off her fit physique in the chicest of way Thursday night at celebrity trainer Tracy Anderson's flagship studio opening in Brentwood.
Red lips, soft golden waves and nude Giuseppe Zanotti sandals added the finishing touches to Stacy's red carpet look.
So…who's ready to hit the gym for an hour or five? Ha!
