Kyle Sandilands: I had sex with Imogen Anthony in that Fashion Week mask last night

Imogen Anthony certainly turned heads when she arrived at Mercedes-Benz Fashion Week  wearing a bedazzled full-face mask on Tuesday.

And now, boyfriend Kyle Sandilands has revealed exactly what went down at home after her peculiar appearance. (Hint, it didn't involve hanging up her mask).

"I had sex with her in it [the mask] afterwards last night,' the 45-year-old shock jock announced live on-air during his KIIS FM radio show on Wednesday morning.

Of course co-host Jackie 'O' Henderson was quick to react saying, "Don't say things like that, darl -- she's not going to be happy you've said that." 

"She's fine with that," Kyle declared.

Either way, 26-year-old Imogen revealed she chose to wear the mesh mask because she couldn't be bothered putting on makeup that day.

And it seems the Instagram star doesn't use a stylist, either.

"I pick everything out myself," she told The Daily Telegraph. "If you can't do this at fashion week where can you.

"It's fun, it's good to celebrate Australian fashion and wearing this makes me happy."

Imogen has been a regular fixture at Fashion Week, serving up some truly eccentric ensembles.

On Sunday, she kicked things off by gatecrashing the Sydney Opera House forecourt ahead of Dion Lee's opening show.

She joined an entourage of local models as they attempted to coordinate an unauthorised runway to launch independent Australian designer Joshua Mullane's Psuedo collection.

And after she showed off her crystal headgear on Tuesday, she slipped into a pair of thigh-high boots, and a red Cruella de Vil-style fur coat.

While some outfits have been fairly outrageous, it certainly adds an interesting touch among all the beige.
