Jennifer Garner Plays the Saxophone for Reese Witherspoon's Birthday in Jazzy Tribute Video

Jennifer Garner is celebrating pal Reese Witherspoon with a musical tribute.

As Witherspoon marked her 48th birthday Friday, Garner shared a video on Instagram showing herself playing saxophone outside in sunglasses.

As she played the instrument, a montage of photos of the Yes Day actress, 51, and Witherspoon popped up on screen.

"Two things I love: @reesewitherspoon and smooth jazz. Happy birthday, RW! XX," Garner wrote in the caption of her post.

Witherspoon reposted the video to her own Instagram Story, alongside crying-laughing, red-heart and trumpet emojis.

"🎉🎂🥳🎈Today is an especially special Friday because it’s @reesewitherspoon’s birthday!" wrote Spencer, 53, alongside a photo of the pair.

She addressed her fellow Oscar winner, "Thank you Reese for always honoring all women, everywhere!" and concluded her tribute, "Please join me in the comments in wishing Reese the happiest of birthdays 😄🎈🥳🎂🎉."

Sharing a snapshot of herself on the beach, Witherspoon wrote in her own caption, "Feeling very grateful for all the wonderful birthday wishes! 💗🤗 Thank you to all of YOU who send me love and light from all over the world ✨💫🌟."

To celebrate her birthday last year, Witherspoon shared three photos of herself posing with her dog Minnie Pearl and several bouquets of flowers while thanking her followers for birthday wishes.

"Thank you for all my wonderful, loving, heartfelt birthday wishes. Feeling very grateful for all the LOVE in my life!" she wrote at the time.

Witherspoon attended the 2024 SAG Awards on Feb. 24. The previous month, she brought her son Deacon, 20, to the Golden Globes ceremony as her date; daughter Ava, 24, joined her mother on the red carpet at the Critics Choice Awards that same month.

The actress last appeared on screens in the third season of her Apple TV+ series The Morning Show, in addition to her 2023 Netflix rom-com Your Place or Mine. She also has a number of projects — including the long-awaited Legally Blonde 3 — in development.
