The 'Wild' star has revealed 15-year-old Ava loves sharing wardrobes with her and the pair will regularly dive into each others' closets for their outfits of the day.

When asked what she's allowed to wear from her closet, she said: "Anything she wants to wear. She and I just swap clothes.

"She's got great taste. I love to see the way she has her own sense of style. She's a young woman and is really developing her sense of what she wants to look like."

Their similar sense of style has been the basis of many shopping trips recently, with Reese and Ava - who she has with ex-husband Ryan Phillippe - unable to resist trips to their favourite stores.

She added to PEOPLE magazine: "We actually both love the same hats, that's what's funny. And we both love makeup. We go to Sephora maybe way too much. Ridiculous. But it's fun - it's great to have a girl and get to go shopping together and buy makeup and stuff ...

"I really trust and value her opinion; she's a very smart young woman and she helps me make a lot of decisions."
