Ava Phillippe Reveals the Best Beauty Advice She's Received from Her 'Southern' Mom Reese Witherspoon (Exclusive)

Ava Phillippe takes her mom’s advice to heart.

The new face of Vince Camuto Wonderbloom fragrance, 24, especially listens to mom Reese Witherspoon when it comes to beauty advice.

“My mom is Southern,” Phillippe tells PEOPLE exclusively while chatting about her new role with Vince Camuto. “A big saying in the South, especially amongst women is, ‘Pretty is as pretty does.'”

For Witherspoon and Phillippe, that means embodying good values all around because “beauty” isn’t just surface level.

“Every time that comes up in my brain or I see people bring critical of others online for their appearance, I just always think, you’re only as beautiful as you treat other people,” Phillipe, whose dad is Witherspoon’s ex Ryan Phillippe, shares. “As we move through the world, I find that beauty is really subjective, but what’s not is being kind and being open and treating people with respect. I think that you glow from within when you’re a good person.”

The lookalike mother-daughter duo have been enjoying fashionable events together in recent months, including sitting front row at the Fendi Haute Couture show in Paris in January. Witherspoon, 47, wore a black high-collar dress with flared skirt, while Phillippe provided a pop of color in her yellow turtleneck and gray skirt combo.

They both carried matching Fendi bags and posed for photos outside the venue in their complementary sunnies.

Just days prior, they walked the red carpet at the Critics Choice Awards, where the Morning Show actress was nominated for best actress for her role in the show. They truly took their twinning game to the next level in their coordinating all-black looks, with Witherspoon in a floor-length strapless black Celine dress (with a thigh-high slit!) and Phillippe in a pearl-adorned black Monique Lhuillier minidress.

Witherspoon shared their looks on Instagram, writing, “Mother daughter date night.”
