Jennifer Garner just took 50 rounds of the sun, celebrating her 50th on Easter Sunday.

Celebrities poured in their wishes for Garner, and she also got a very special pre-birthday surprise.

She posted a video of the cutest farm animals jumping around in glee - with a pony, a lamb, and the most adorable llamas.

Right before she shared the Instagram post of the cutest and happiest baby animals jumping around, Garner honored her children with the sweetest Instagram story

Garner wrote, "there is no doubt that the center of my gratitude stems from the health, humor, and adorable-ness of my kids.”

She went on to say that she was very lucky to have them in her life, and was “prayerfully grateful” for them.

Many celebrities wished her a happy birthday with Reese Witherspoon writing: "Happiest Birthday to our happy little farm girl!”

Garner also got a lovely pre-birthday surprise from someone she idolized as a child.

Garner shared a clip on Instagram where she seemed to be completely floored as she watched a video of Donny Osmond singing to her before he popped up behind her.
