Reese Witherspoon celebrated her older brother John Witherspoon's birthday with an epic throwback photo.

The pic appears to be taken at a wedding, as John is sporting a tuxedo while a very young Reese is wearing what could be a bridesmaid dress. "Aren't big brothers the best!? #HBD to this guy who has the biggest smile," she captioned the sweet pic. "Thanks for being by my side all these years. I love you! (Fun fact: he also makes the BEST ribs in Nashville! ?) #BigBrother."

This wouldn't be the first time the 40-year-old actress has doted on her big bro. In November 2014, she shared a pic of herself and John at a restaurant in Nashville. "Love seeing my brother," she wrote. "He shares my love for doughnuts and that's how I know we are related."

Reese loves to post pics of her family on Instagram, and just last month shared a photo of herself, husband Jim Toth and her three children, who look just like her, celebrating Tennessee's fourth birthday.
