Reese Witherspoon’s daughter Ava Phillippe, 21, goes for a jog with her rescue dog in Brentwood

Ava Phillippe looked just like her famous mother as she took a vigorous jog around her Brentwood neighborhood on Monday afternoon.

As the 21-year-old daughter of Reese Witherspoon and Ryan Phillippe went for a run with her dog, she wore a white sports bra and black leggings. 

While working up quite the sweat, Ava styled her bright blonde tresses in a high ponytail and listened to music through a pair of wireless headphones. 

She was vigilant about keeping her close and mouth covered amid the COVID-19 pandemic, and only took off her face mask to catch her breath. 

Since rescuing her Border Collie mix, Benji, in October, the sophomore at UC Berkeley has been practically inseparable from her four-legged friend.

Her parents, who divorced in 2008, and 17-year-old brother Deacon are also avid runners. 

Additionally, Witherspoon is a mom to an eight-year-old little boy, named Tennessee, who she shares with her talent agent husband Jim Toth. 

In March, the 44-year-old Big Little Lies star and and Toth will ring in their tenth wedding anniversary.

Last year, the mother-of-three said it was ‘weird’ seeing her firstborn ‘go away to college’ on the Ellen DeGeneres Show. 

‘It’s hard. I never imagined how it felt for my mom. I might have gone into [Ava’s] empty room, laid down on her bed and cried when she went to college,’ the Oscar winner admitted.  

While Ava hits the books, Reese’s son Deacon is currently pursuing a career in music and dropped his first single, Long Run, seven months ago. 

Witherspoon regularly updates her fans on their experiences quarantining as a family, which has included wearing matching sweaters, family dinners and adopting new pets.
