Sasha has dated since his Bachelorette ex - the construction manager debuted his previous romance with girlfriend Tori May on Instagram in November 2018.
"Of course I found her at the Berry donut van #emojigamestrong," he captioned a cosy photo of himself and Tori.
"Happy 40th Birthday @torimay! I feel extremely grateful to have such an amazing, caring and compassionate lady in my life."
"I love hanging out and talking shop even if it means I have to listen to one of your less interesting stories! Hope you have an amazing day," he concluded.
Home and Away star Sam unleashed on her ex via a sneaky comment in December 2019, seemingly confirming rumours that Sasha cheated on her.
The comment was left on a Buzzfeed article entitled: "25 Reasons People Gave For Cheating That Are, Somehow, More Disrespectful Than The Act Of Cheating".
She even tagged his most recent ex Tori, writing: "@_torimay_ he once said Instagram must have hacked his account that's why he had followed and messaged all these girls."
Tori replied: "@fro01 omg what. Master of lies and manipulation. The lies he told me still blow my mind."
Though Sasha's name was never mentioned, fans understandably went into a frenzy.
Sasha and Sam dated for 18 months after he won her heart in Australia's first ever Bachelorette finale in 2015.
When rumours arose that they only stayed together for "contractual reasons", the season one winner slammed claims, calling them "ridiculous."
"No such thing exists. I mean, Sam and I fell in love. And I still love her. She's an amazing person," he exclusively told Who in 2017.
"We fell head over heels in love from the moment we saw each other. There was no way that wasn't real."
