Jennifer Aniston's reaction to ex-husband Brad Pitt at the SAG Awards wasn't the only reason why the "Friends" actress made headlines at the Sunday night show.

The actress, 50, turned heads in her hip-hugging white satin slip dress from Christian Dior by John Galliano.

Aniston took home the award for outstanding performance by a female actor in a drama series in Apple TV's ''The Morning Show.''
