Tim Robards got very cheeky about Anna Heinrich's nude photoshoot on the ARIA red carpet.

We’ve all been there. Your partner opens his/her mouth and says something completely awkward or embarrassing in front of someone you’ve just met.

Well, spare a thought for Anna Heinrich. Last night her Bachelor beau Tim Robards did just that in front of a journalist – and therefore, the entire world.

The couple were being interviewed while walking the ARIAs red carpet, when a reporter from Nine’s The Fix raised the 29-year-old’s recent nude covershoot for Women’s Health magazine.

Turns out she didn’t want Tim present on the day, but the chiropractor had other ways of helping out.

“We did a lot of practice around the house,” he joked.

“I’m like, ‘Walk around, take your clothes off’.”

Anna’s hand was planted firmly on her hip by this point, but Tim pressed on, confirming he gave her a few tips ahead of the shoot.

“You don’t want to see the poses!” he laughed. (Post continues after gallery.)

Before he could get another word out, Anna slammed her hand across his mouth, and added diplomatically, “Everybody has been so positive. And I am so grateful and I am so thankful I did it, because spreading confidence – that’s what it’s all about.”

(You can probably see where this is going…)

“It’s not the only thing that was spreading!” chimed Tim.

And – whoomp – there it is.

“Oh my God! Tim, honestly,” Anna said. “What is wrong with him?”

He’s a boy, Anna.
