In one of the photos, a shirtless Seb stood behind Elizabeth as she leaned against the kitchen counter with a big smile on her face.
While the couple weren’t having sex, fans were quick to question whether the lovebirds were getting frisky.
'The angle of the picture says a thousand words,' one fan wrote, while another added: 'That pic looks dodgy.'
A third commented: 'That first photo is poorly positioned.'
Several others agreed the images looked 'suss' and 'questionable'
Even Seb agreed that the angle of the photo was unfortunate.
Only we could make preparing pumpkin soup look so questionable.' He captioned the images.
Last week, Lizzie addressed why she and Seb weren’t living together.
'People are like, "Why are you not at Seb's place?" I was there last week but got a phone call that I had to be in Sydney for work,' she explained.
'So I left South Australia. I'm now in quarantine. I have to do my work thing and then I'll have to be in quarantine again [when I go back to Adelaide]. That's just life. Coronavirus puts a lot of stress on a lot of different aspects. Yeah, it's hard.
'Obviously you have everything to do with MAFS and a new relationship, and then you have to go back and forth.'
Elizabeth added: 'Seb was moving to Sydney, but that's a lot to get organised and doesn't happen overnight. He is based in South Australia.
'I thought I'd be based in Adelaide for the time being but my work stuff is in New South Wales. Coronavirus has [had] a huge effect on a lot of people.'
