They've been busted more than once 'liking' each others' Instagram photos.

But this week, Married At First Sight's Telv Williams and The Bachelor's Zilda Williams went from double-taps to comments as they flirted up a storm on the social media site.

The pair's sweet exchange started when Zilda posted a busty selfie to celebrate her 35th birthday.

'Happy birthday, enjoy those celebrations and family time,' commented Telv.

Zilda quickly responded: 'Thanks babe. The big 35!'

Telv, clearly stunned by learning Zilda's true age, then gushed: 'No way in the world you are 35!?!?! I don’t believe you lol. You don’t look a day over 25.'

The Married At First Sight star has been open about the type of women he's into, and Zilda certainly fits the bill.

The Kiwi-born beauty, who first shot to fame as a men's mag centerfold, is famous for her voluptuous curves - specifically, her EE-cup assets.

Telv, who was 'married' to Sarah Roza on MAFS, repeatedly complimented her curves during his time on the show, making it clear that it was a big part of why he was so attracted to her.

'Well, I do like curves in a woman,' he admitted during an appearance on Today Extra with 'wife' Sarah, before adding: 'And I definitely got the curves, didn’t I!'

In early March, the single dad was caught liking a number of Zilda's busty selfies on Instagram.

The pair are both currently single, with Sarah announcing her split from Telv last month, while Zilda followed shortly after by confirming her breakup with her much younger boyfriend Keith Frazer after almost a year together.

Unfortunately, Zilda recently moved back to New Zealand, while Telv currently lives between Perth and Melbourne.

Single and ready to mingle! While Zilda never received a rose from Sam Wood on The Bachelor, the bombshell could find love with Telv now that the pair are both officially single
