"And here it is-never thought I would get caught off-guard," she captioned the video.

The actress' gratitude at her husband pulling off the surprise was evident with some of the photos she posted, as she happily called the event her best birthday ever.

"Just when I thought no one could EVER surprise me, Mr. Sweeting goes and does it. Best birthday of my life/thank you to everyone involved-you know who you are," she captioned a collage photo of herself and her husband sharing a kiss and a shot of the table centerpieces.

And much like the customized cake she provided her husband at his surprise July birthday event, Sweeting also commissioned a custom cake for his wife, a three-tiered confection with black frosting and gold stencil designs with a horse, and other swirls.

 Thank you to @thebutterend for the most perfect horsey cake a girl could ever want!
