She split with her first husband, AFL star Brad Miller, back in 2016, and went on to marry millionaire Hollywood agent Patrick Whitesell in 2021.
But Pia Whitesell is still friendly with her ex Brad, and was seen attending the UFC in Sydney with the two men.
They trio were also joined by Pia and Brad’s son Lennox, 16, and the Home and Away star’s eldest son Lennox, 20, from a previous relationship.
The group appeared to be getting along famously, with Patrick seen shaking hands with Brad before the pair enjoyed a light-hearted chat.
Brad, who usually shies away from the spotlight, also happily chatted with Pia as well as Isaiah and Lennox, who looked thrilled to be spending time with him.
Pia and Brad were married from 2007 to 2016.
The actress went on to marry American talent executive Patrick in 2021, and has since relocated to Los Angeles.
The modern family were there to watch middleweight fighters Adesanya vs Strickland at Sydney’s Qudos Bank Arena at the city’s Olympic Park.
Pia, 39, looked stunning in a pair of tailored forest green trousers and a suit jacket, which carried over her forearm.
She paired the suit with a tight-fitting black Prada top.
The former Home and Away star accessorised with a pair of designer sunglasses and she carried her belongings in a Celine handbag.
The star accentuated her natural complexion with minimal makeup and wore her brunette tresses down.
Patrick opted for a pair of jeans and a black long-sleeve t-shirt and some designer shades.
Brad also opted for a black t-shirt and trousers paired with sneakers.
Despite enjoying a high-profile career and romance with Pia for almost a decade, Brad now lives a more reclusive life away from the cameras.
He made a move to the Gold Coast Suns as an assistant coach ahead of the 2022 Premiership season.
He lives 10 minutes from his mother and 12 minutes from his father and is “very close” to both, according to AFL Queensland.
With Lenny in Los Angeles, his home life is devoted to three-year-old daughter Indie, born April 2020, and wife Daisey, a successful business executive.
