A modern family! Jono Castano shows off his toned physique while working out with his ex-wife Amy’s soccer star boyfriend Aaron Evans – after she called his girlfriend a ‘sister’.

Celebrity personal trainer Jono Castano was spotted sweating and working out at a park with his ex-wife Amy’s new boyfriend Aaron Evans on Wednesday.

Jono, who has coached Rita Ora and Rebel Wilson, among others, showed off his toned physique in leggings and a Nike shirt, covered with a beanie.

Aaron, who plays professional football, showed off his muscular arms and tattooed sleeves in a tight Nike singlet and white shorts.

The pair were spotted running an oval in Coogee and fist bumped throughout the session, appearing to be coping well.

Aaron also works out at Jono and Amy’s gym, Acero, which they still jointly own after their breakup.

Jono has just returned from a trip to the Maldives with his model friend Simone Holtznagel, who turned 30.

Before the trip, Jono and Simone got together for a lavish birthday dinner with his ex-girlfriend Amy and Aaron.

In a series of cheerful snaps posted to Instagram, Amy kept referring to the socialite and model as a “sister” while the beauties sipped on some bubbly drinks.

The cheerful foursome were all smiles as they enjoyed the early birthday celebrations and once pulled out a white frosting cake topped with maraschino cherries.

“Happy birthday to the sister I won,” the brunette beauty captioned one photo, while in another she simply wrote, “Happy early birthday sis.”

Jono made his debut with his new girlfriend Simone in September.

Amy (left) and Jono Castano, both 32, split in 2021 but there’s clearly no bad blood between them as the influencer happily calls his new girlfriend, 29, (right) her ‘sister’.

Their relationship became public knowledge after they were photographed kissing at Mimi’s, the celebrity hotspot of hotel mogul Justin Hemmes, who is dating Simone’s sister Madeline, in May.

The Castanos split in early 2021 but decided to keep up appearances before making an official announcement.

Although the ACERO gym co-owners are no longer together, they remain friends and continue to run their fitness empire together.

They are often seen out and about, where they eat and go for walks together.

“We just want to say that we really, really respect each other and that we really appreciate your patience,” Amy said in June last year, just a day after opening up about her romance with 28-year-old Aaron.

“Obviously we’ve been through it together for a while and we’ve had fifteen years and there’s nobody else on this planet I’d want to carry on this baby with, that’s ACERO.”

The estranged couple first met on MySpace 13 years ago before later meeting at a nightclub and falling in love.
