Fiona Falkiner's fiancée leaves x-rated comment on model's racy lingerie snap

Aussie model Fiona Falkiner, 36, left her social media followers gasping after sharing a racy lingerie-clad selfie on Thursday.

But it seems that The Biggest Loser star's biggest admirer is her fiancée, Channel Nine reporter Hayley Willis.

Blushing bride

The sports journalist couldn’t resist posting a very cheeky comment on her lady love’s saucy snap which was taken on set of a photoshoot in Germany.

“I wouldn’t object if you wore this down the aisle,” she wrote to her partner of almost a year, adding the bride emoji for extra effect.

Fiona responded in kind with a kiss emoji and the words, “miss you xxx.”

Fiona and Hayley’s love story

The high-profile pair went public with their relationship back in January this year after sharing a pic of themselves cuddling up on the beach on social media.

According to Woman’s Day, the couple had been dating for “about four months” at that point, which would see their one year anniversary coming up very soon.

Fiona and Hayley are set to say ‘I do’ after getting engaged while on holiday in Vanuatu in April.

Fiona revealed that Hayley popped the question at sunset on a private beach, gushing, “She asked and I said yes,” on Instagram.

Hayley also shared a black and white close up of the couple’s stunning engagement rings which she captioned “I feel pretty” along with the hashtags “#itsofficial” and “together4eva.”
