'We don't mess around!' Reese Witherspoon treats golf-mad son Deacon to a hole-in-one birthday cake as he turns 12 

Reese Witherspoon pulled out all the stops for her golf-loving son Deacon's 12th birthday.

The Wild star posted a photo on social media showing off the green hole-in-one birthday cake she'd created for the youngster complete with a sand bunker, lake, hole, flag and golf ball.

'When it's my sweet, golf-loving boy's birthday.....we don't mess around!' she wrote alongside the picture.

Snatch up a floral dress like Reese

Reese Witherspoon feted her son Deacon for his birthday and pulled out all the stops. Not only did she present him a birthday cake that looked like a golf course (the kid loves golf, we're told), but she dressed up for the occasion too.

Reese can often be found wearing her own line, Draper James, and, on Friday, when she was snapped in this pic, that was no exception. She's wearing the Hollis cross-front fitted dress and we love the bright fuchsia lotus flowers against a white background. Another detail that caught our eye is the cross-front halter neck with straps that continue down the back.

The good news about Reese's pick is that it's available to buy now. Just click right to buy. You can also snap up Reese's earrings, too, a collaboration with jewelry-maker Erickson Beamon.

If you'd rather do some window shopping first, see below. Because, even though it's fall, there are still quite a lot of floral frocks for the taking.

The Hollywood star also shared a photo of herself wearing a pretty floral dress standing with her arm around Deacon, who was dapper in a bow tie and blazer.

She wrote a sweet message to her son alongside the snap, telling him: 'You bring joy to everyone you know. I feel so blessed to be your mom.'

Deacon's dad is Reese's first husband, actor Ryan Philippe, and he has an older sister Ava, who's 16.

He also has a younger brother Tennessee, three,  whose dad is Reese's husband, talent agent Jim Toth.
