Piggyback PDA! MAFS lovebirds Gia and Scott can't keep their hands off each other as they step out for lunch at Bondi hotspot Totti's

Married At First Sight couple Gia Fleur and Scott McCristal haven't been shy about showing their affection for each other from the moment they entered the experiment.

And even when they are away from the cameras, the loved-up pair can't seem to keep their hands off each other.

In exclusive photos, the couple got amorous after they enjoyed lunch at trendy Bondi eatery Totti's during filming last year, with Scott seen piggybacking his bride out of the eatery.  

The couple seemed giddy in love as they beamed hand-in-hand and played it up for the camera. 

Gia, 35, dressed casually for the outing in jeans, a white cropped tank top that showed off her tattoos and a pair of cream trainers.

She accessorised with layered wrist bracelets and tinted designer sunglasses. 

Meanwhile Scott, 33, matched her look with a blue denim shirt over a white singlet, skinny black jeans and white sneakers.

The affectionate outing comes after Gia raised eyebrows when she brazenly bragged about her sex life with Scott on camera.

'It was an instant connection between me and Scott. We didn't want to have sex straight away, so we waited until day four,' Gia proudly told her co-stars.

'We tried to hold off, but we couldn't! I feel like I have known him for a year.'

Her comments sparked a fiery clash with fellow bride Bec Zacharia, who appeared visibly irritated as Gia gushed about her bedroom antics.

'Shut up! She feels like her relationship is so good right now and she is in this dream place. Like, I am really happy for her that she had good sex, but to see her with that massive smile on her face… shush! Like, read the room,' Bec vented to producers.

The tension escalated when the brides began competing over whose honeymoon was superior, with Bec boasting about her week in

Fiji while Gia and Scott revealed they travelled to Townsville.

'Gia and Scott went to Townsville… Not Fiji! I'm sure they had a nice time though,' Bec quipped.

A furious Gia later fired back.

'Bec is yuck! Like what is your f***ing problem? It was just rude, she is rude!' she said.

'You know what, Townsville was lovely. And it seems we got on better than you and your man!'

Despite the drama, these latest photos suggest Gia and Scott's bond remains unshakeable.

In a previous chat with Daily Mail, Gia described their connection as electric from the outset.

'It was an instant connection,' she said.

Scott has also made no secret of how smitten he is with his bride, with insiders revealing the pair have grown even closer since filming started.

'They are obsessed with each other,' a source close to production previously said.

'What you see on camera is very real. Off camera, they are even more affectionate.'
