Best known for her 1990s comedy series "Suddenly Susan" role Maddy, Bendewald starred with Aniston in the 1997 film "Picture Perfect,"

Bendewald also appeared in "Friends" in the 2001 episode "The One With The Cheap Wedding Dress" in which she played the ruthless bride-to-be who fights with Monica (Courteney Cox) for a wedding dress at a bridal store.

In a recent interview with Glamour magazine, Aniston said her best hairstyle of all time is "long, natural-looking beachy waves" because it feels most like her.

About her no-fuss daily hair strategy, Aniston told the magazine that she will wash her hair, wash it, brush it, then put styling cream in and let it air-dry on its own. She also shared that her overnight beauty trick is to put Living Proof Night Cap Overnight Perfector on her hair before bed.
