Reese Witherspoon’s Son May Have Just Turned 7, but I Swear They’re Twins

Reese Witherspoon shared a sweet Instagram snap in honour of her youngest child, Tennessee, turning 7 on Sept. 26, and whoa, are they twins?! It's well-known that Reese and her oldest child, Ava Phillippe, look so much alike it's scary, but now that Tennessee — whom Reese shares with husband Jim Toth — is getting a little older, it's hard to deny the resemblance he bears to his mama. (Sorry, Jim Toth and Ryan Phillippe, but Reese must have reaaaally strong genes!)

"Boy, this kid makes me laugh! Happy 7th birthday to my sweet boy Tennessee," Reese wrote to Tennessee on Instagram. "Here's to a day filled with chocolate cake, Beyblades, and dog cuddles!" Happy birthday, Tennessee!
