Meanwhile, as Eleanor and Aidan promote the latest series of Poldark, which starts airing at 9pm tonight, it appears that their work commitments have given them a close bond.
When asked for a comment, Tara initially declined before then saying it wasn't her in the pictures.
In the images the pair appeared completely smitten, with the curly-haired hunk showering her with affection.
"Me and mum don't talk about steamy stuff - at all.
I never get women throwing themselves at me, never." Aidan has been single since his split from fellow actress Sarah Green last November – they dated for five years.
BBC1 star Aidan, 33, and Nettie were first pictured together in London last October, sharing a passionate kiss after enjoying drinks at a posh members club in the capital.
