Erin Heatherton might be ousted for being "difficult to work with," reports Stephanie Smith at The New York Post.
Heatherton famously met her now-ex-boyfriend Leonardo DiCaprio at the show two years ago.
Miranda Kerr was reportedly ousted from the brand under similar circumstances earlier this year.
Kerr, the wife of actor Orlando Bloom, had a "difficult" reputation and wasn't a big seller like Alessandra Ambrosio and Candice Swanepoel, according to a report by Joyce Chen at UsWeekly.
Reps from Kerr and the brand denied that the split was acrimonious.
Still, Kerr is noticeably absent from the fashion show line-up this year.
The company hasn't commented on final details for the show, which tapes November 13.
