Reese Witherspoon shows off a homemade cake complete with dump trucks and construction cones for son Tennessee's third birthday 

She is reportedly worth $80million.

But when her three-year-old son Tennessee needed a birthday cake, the 39-year-old star seems to have gotten busy in her own kitchen to whip one up.

On Sunday the Wild star shared an image of a lopsided spectacle - which did not look as if it was made by professional bakers - complete with dump trucks filled with mini M&Ms and orange construction cones. 'It's all about the cake,' the mother of three wrote in her caption.

The photo's description read: 'Happy Birthday Sweet boy! 3 is a magic number,' along with balloon emoticons.

He had on a blue and white shirt with big blue sunglasses.

Reese Witherspoon is a woman on the run.From acting and running her Draper James clothing line to setting up a birthday party for her little boy...but that doesn't stop Reese from looking mighty fine.

The blondie stepped out looking sophisticated as usual and although she's a walking billboard for her Draper James brand, the only thing she donned in this ensemble was her brown bag.

Bag and clothing aside, we're obsessed with her two tone sunnies. We've seen Reese rocking these more than once and we don't blame her, they're stylish!

Selling everything from clothing to home decor, Reese recently revealed that she had set her sights on introducing bridal wear to the company.

'We're looking at children's and shoes and bridal. A lot of women want bridal. There's a thing about the Southern bride. It would be a lot of fun to create wedding dresses and I have a lot of experience with that whether it's in movies or real life,' she told Today.com
