Love Island star Matt Zukowski has gone Instagram official with his girlfriend Tammy Hembrow.

The couple were seen getting hot and heavy in a photo shared to Instagram stories on Wednesday before walking the red carpet at the premiere of Stan Original series C*A*U*G*H*T in Sydney.

The reality TV star, 28, wrapped his arms around his new girlfriend for the selfie as he kissed her forehead.

Tammy looked glamorous in a black dress as she posed alongside her beau for the camera.

The post came just hours before the couple put on a loved-up display at the premiere of Stan’s C*A*U*G*H*T in Sydney.

Tammy showed off her figure in an all-black ensemble for the evening, consisting of a black slip dress with a high-low hemline.

She accessorised her look with a chic black Chanel handbag and boosted her height in a pair of towering heels.

Elsewhere, Matt donned a navy suit and white shirt unbuttoned at the collar.

Last week, Matt confirmed his new romance with the influencer by admitting he was ‘falling’ in love with Tammy at a taping for his podcast Where’s Your Head At? at The Vanguard in the inner city suburb of Newtown.

The reality star expressed his feelings towards the blonde during a Q&A session with audiences at the event – and her reaction was caught in video obtained by Daily Mail Australia.

‘I’m falling [in love],’ he admitted as Tammy and her half-sister Starlette Thynne sat in the crowd.

Starlette then responded: ‘I don’t accept that answer because as a sister I feel like it needs to be a yes or a no.’

‘Well, I have a Uno deck and I’ll reverse it. I’ll reverse that question,’ Matt joked.

Elsewhere, Matt was grilled about whether he was single when he was surprised by a question from Starlette.

‘Are you in love with a girl with a bob and three children?’ she asked and Matt confirmed he was, saying the woman was in the room with them.

A shy Tammy then shook her head, before Matt confessed that the pair were taking things slow and were exclusive.
