Osher ended the post by asking fans to comment and tag their single bestie for their chance to be on The Bachelor.
I'm A Celeb alum Jack quickly followed instruction, penning "Applying now" below the post. While he was probably kidding, Jack is definitely of reality TV pedigree, having starred now on Australia's Got Talent, The Voice, The Masked Singer, and I'm A Celebrity ... Get Me Out Of Here!
But the singer may have his competition cut out for him, considering which *other* celebrity was tagged in the comments.
Ever the matchmaker, Bondi Rescue's Andy Reid tagged his co-star Harrison Reid for a chance to join the dating game.
Last year was the ninth season of The Bachelor, with bachie Jimmy Nicholson choosing Holly Kingston as his winner.
Still together today, the couple mark the fifth successful pairing to come out of the Australian franchise.
While confessing there were some "tough moments" when watching the season back, Jimmy and Holly feel blessed for the way they met.
"For the most part, we're just really lucky that our love story has been documented to show the kids one day," Holly told our sister site TV WEEK in September 2021. "In a weird way, along with dad kissing other girls (laughs)."
Jimmy added: "It's kind of funny when people say 'oh, they're going to break up' and we're just like, yeah? Watch this'."
