She's been spending time with her rumoured new boyfriend Nathan Brodie.

But on Saturday, it was back to mum mode for Nadia Bartel, who spent some quality time with her sons Henley, one and Aston, four.

The 35-year-old designer shared a series of photos to Instagram, while building a cubby house for her two boys.

She also shared another picture of her two boys finally playing after the cubby house was built.

Nadia's post comes after she went Instagram official with her long-rumoured 'secret' boyfriend, Nathan. 

On Friday, Nathan shared a photo to Instagram showing the former WAG relaxing on the beach in a skimpy bikini.

The personal trainer captioned the photograph simply: 'Days in the sun'.

In the picture, Nadia wore a snakeskin bikini that showed off her ample bust, and covered up her face with a sun hat.

The couple have been keeping their relationship under wraps for some months.

Nadia and Nathan's fling hit the headlines in September, when the pair were pictured together in Melbourne on two separate occasions.

Nadia and her ex husband Jimmy Bartel announced their separation on August 15 last year, but they are believed to have actually split two months earlier.

They share custody of their two young sons Henley and Aston. 

The retired Geelong Cats star has since moved on with new girlfriend Lauren Mand.
