It's Reese Witherspoon
The 38-year-old actress grew up in America's deep south, in the state of Louisiana. She captioned the photo of her as a child on her Instagram account: 'Because what Southern girl doesn't love a John Deere tractor.'
Reese found fame in the box-office hit Legally Blonde. She married Jim Toth in 2011 (remember their slightly embarrasing run-in with the law in 2013?), has three children, and she's also global ambassador for Avon.
