The engagement was announced exclusively live on RTÉ Radio 1 when Tanya revealed the big news to Ray D'Arcy: "So, on Sunday, I was looking at all my VT, going back in the last eight weeks and Mark came on saying he was proud of me. And he just said, 'Can you turn around? I've one more question to ask you’. And there he was, down on one knee."

Cue excited whoops in Studio 10. Tanya had no idea the proposal was coming:

"I was afraid to turn around, 'cos in my head I was like, ‘He’s going to propose. Imagine if I turn around and he’s just standing there, like, with flowers’."
