Nadia's estranged ex-husband Jimmy echoed a similar sentiment on his Instagram, writing alongside a few happy snaps: "Happy Birthday my now very big boy Aston. You make me laugh everyday with your amazing imagination and you even laugh at my bad dad jokes. You make proud and how happy and excited you are every day and especially how much you love your little brother Henley. Have a great day my Batman #Astonturns4."
While we're not sure what they have in store for their son's big day, it appears as though Aston will be spending time with his mum as she shared footage of herself collecting Batman-themed balloons last night.
While they were once a very influential "power couple" Nadia and Jimmy were thrust back into the spotlight in August after they confirmed they'd called time on their four-year-long marriage. Speaking about the breakdown of their marriage in September, Jimmy admitted their current situation "is not great".
"I am probably not going to provide any commentary on it," he said. "I know I am in the public eye and people are interested, but it is a private matter and I ask for a bit of respect because obviously Nadia and the boys [are] involved.

Since then, all eyes have been on Nadia as more interesting details about the footy player's new girlfriend, Lauren Mand, come to light.
Despite the intense public scrutiny that's come with their romance, the Melbourne socialite doesn't seem too fussed about people's concerns. In fact, last week Lauren— who alluded to secretly dating Jimmy while he was still married to Nadia— shared another photo of the dad which was taken during their romantic holiday in Yarrawonga, Victoria.
She captioned the half-naked photo of her man, "Take me back to swimming with you.
Lauren—who has been branded by insiders as a "want to be WAG"— went public with their relationship earlier this, making their romance Instagram official with a photo of the couple cuddling up to each other. As expected, the post attracted a lot of attention, with one of her followers commending her for "keeping it classy".... which, side note, seems to be a direct dig at Nadia.
"So happy for you, my darling Loz," one pal wrote. "Good to see you guys happy and enjoying life."
Another wrote: "Really happy for you, love that you kept it classy."
