‘It’s All About That Cake!’ Reese Witherspoon’s Son Tennessee Turns 3

Three has never looked cooler.

Reese Witherspoon‘s youngest child, son Tennesseeis starting his third year off in style.

The toddler, Witherspoon’s son with husband Jim Toth, celebrated his birthday on Sunday with some awesome shades.

In a photo shared to the Oscar winner’s Instagram, Tennessee posed in blue sunglasses and a white printed t-shirt that appeared to say, “Awesome.”

The 39-year-old’s little boy held a cup and dug his barefoot toes into the sand.

“Happy Birthday Sweet boy! 3 is a magic number,” Witherspoon captioned the pic.

The highlight of Tennessee’s big day? Definitely the killer chocolate cake.

“It’s all about that cake,” the Wild actress wrote on the photo sharing site.

The mouth-watering confection included thick frosting and M&Ms and was topped off with mini toy construction trucks.

The actress – who also shares children Ava, 16, and Deacon, 12, with ex Ryan Phillippe – and her son certainly know how to have a good time. Earlier this month, the star released a video goofing around with Tennessee on lip-sync app Dubsmash.

The pair took turns mouthing the lyrics to Raffi’s 1994 tune “Bananaphone” – a performance complete with props!

He is actually starting his fourth year.

Beautiful boy but she can just go away… Reese showed her true colors in that police video – she’s an entitled twit.

I guess she thinks she’s someone special.

I totally agree with Zane. Lost all respect for her after that incident. Will never see any of her movies again.

Zane hit the nail on the head!

I don’t think anyone has forgotten what she said to the cop but this is about her CHILD people. In that area, I think she does a good job.

Tennessee? Really? Couldn’t she name her child something more respectable? Because I wouldn’t even interview an adult named Tennessee if his resume came across my desk.

Birthday is spelled wrong on the cake.

@fieldhockeygk11 Her family is from Tennessee, where she was born and grew up. There is nothing that is NOT respectable about the name Tennessee. It has significance to her. It isn’t a made up name or a common name spelled strangely in a feeble attempt to distinguish it from the other 200,000 (e.g. Brittney, Brittany, Brittnee). Besides, no one respectable would want to work for someone who prejudges applicants based solely on their name rather then their qualifications.

Zane- She apologized for that (and seemed very sincere about it). Why continue hating on her for ONE mistake?!

Anyway, happy birthday, Tennessee!
