The apple truly has not fallen far from the tree in the Witherspoon household.
The 17-year-old had no trouble turning heads as onlookers reveled in the likeness she shares with her film-famous mother.
Phillippe attended the event in a Chanel outfit that paired a green top with eyelet details to a pair of multi-coloured cuffed shorts.
The far-too-well-dressed-to-be-17-year-old accessorised the look with a pair of bejewelled cuffs and a sequinned bag.
The event marks the first time Phillippe has posed for a red carpet without her mother in reaching distance.
It's a pretty concrete effort - no awkward hands (seriously, where do you put your hands in these photos) or weird smiles.
A photo of the teen was later uploaded Instagram where fans couldn't get over how closely she resembled her mother.
