Wedding bells are on the way for Irish TV presenter Amanda Byram.

The 42-year-old took to Twitter last night to share some very happy news with fans, shortly after returning home from a Christmas holiday in Argentina and Chile with her boyfriend Julian Okines.

"Back on home soil after the adventure of a lifetime… Oh… and #GotEngaged!" she wrote, sharing a holiday snap of her holding a glass of Argentinian vino while flashing her engagement ring.

Amanda has been dating London-based TV producer Julian for around two years, calling him "absolutely brilliant" and her "partner in crime."

And if the Irish star's Instagram feed is anything to go by, it wasn't just the proposal that made her recent South America trip the holiday of a lifetime.

"So that's it, after 12 flights, countless hikes, bikes, buses and treks through rain, wind, sun and snow. 20,000 miles from UK across Chile and Argentina into forests, over glaciers, past icebergs. Today the road home begins," she wrote yesterday alongside a collage of holiday snaps.

The Dubliner has spoken before about the possibility of starting a family, though she says she is willing to leave things up to fate.

"I'm fit, I'm healthy, there are no problems in that sense," she said of her hopes of having kids. 

"So who knows? It's in the hands of the gods."
