Jennifer Garner Rocks Marching Band Uniform & Plays "Happy Birthday" On Saxophone For Reese Witherspoon!

Once a marching band lover, always a marching band lover!

Jennifer Garner nailed a rendition of "Happy Birthday" on her saxophone in honor of her pal Reese Witherspoon's __ birthday. In a hilarious video posted on Instagram, Jennifer marches out in her full band uniform, complete with a big hat with a feather topper and white shoes, and she launches into "Happy birthday!"

At the end of the video, a proud-looking Jennifer smiles for the camera. She captioned the video, "Hey, @reesewitherspoon! I don't know why you're on my mind today…..🎷🎁🎈🎈❤️❤️❤️ #happybirthdayfriend."

The video is every bit as awesome as you'd imagine! And we're pretty sure even Bill Clinton would be impressed with Jen's saxophone skills.

Reese sure was! She responded in the comments on Jennifer's video and wrote, "#1 Best Birthday Message" with star and heart emojis.

Jennifer is quickly become one of our favorite Instagram stars since she started her profile in September 2017. She shares a weekly video all about dance on "Tutu Tuesdays," hilariously embraces her nerdy side, shows off her butt-kicking workouts, does cooking segments, and isn't ever afraid to have a laugh at herself.

We love you Jen —and Happy Birthday Reese!
