Tammy Hembrow and Matt Zukowski have long been rumoured to be on the rocks, but the Love Island Australia star has all but confirmed speculation after missing a milestone moment.

The couple have been fuelling split rumours for weeks with an array of cryptic Instagram posts and glaring absences pointing to trouble in paradise.

Matt, who co-hosts the Where’s Your Head podcast alongside fellow reality star Anna McEvoy, posted a picture to his Instagram story on Monday holding her newborn baby.

‘Meeting Suede Staples,’ the 29-year-old captioned the post, accompanied with a blue heart.

In the snap, Matt wore a big smile and an all black ensemble as he held the little one, who Anna welcomed with Michael Staples earlier in June.

However, as Matt cuddled up to Anna’s newborn bub, he was clearly not wearing his wedding ring, a traditional plain white gold band.

It comes as the podcaster was notably absent from Tammy’s daughter Posy’s birthday party, which she hosted over the weekend.

In a series of pictures and videos posted to Instagram, the fitness influencer, 31, also opted to ditch her wedding band and diamond engagement ring as she threw Posy’s fairy-themed third birthday party without her husband.

One clip showed Tammy in a pink lacy tank top as she prepared adorable fruit skewers for her daughter’s birthday bash with a bare ring finger.

Later, she shared a photo alongside her three kids – daughters Saskia, eight, and Posy, three, and son Wolf, ten – this time, wearing a pale green bodycon dress with no sign of the sparkler Matt gifted her when he popped the question last year, nor the band she paired it with when they wed.

The couple married in Byron Bay in November, and Tammy opted for a band of huge glittering diamonds.

An Australian jeweller has estimated that the wedding band would have set the star back a massive $23,000.

Meanwhile, her $46,000 engagement ring features an oval-cut diamond, estimated to be around two carats, which sits on a full diamond band.

Matt has refrained from sharing any recent posts or stories featuring Tammy, further fuelling speculation that the pair may have quietly parted ways.

Sources close to the couple previously told Daily Mail Australia the pair are ‘on a break’, with Matt relocating back to his native Melbourne while Tammy remains in Queensland with her three children.

Matt also ramped up rumours that his whirlwind romance with Tammy may be over after posting footage of himself going to the movies solo in recent months.

He took to Instagram to share a video from inside the cinema, revealing he was watching Death of a Unicorn alone – a move which came after fans noticed he was absent from Tammy’s 31st birthday celebrations.
