Miley Cyrus pretended to be an Australian reporter called Janet for the sketch on Jimmy Kimmel Live.

Despite her Southern drawl, Miley Cyrus actually does a pretty good Australian accent.

The 22-year-old singer went undercover as an Australian reporter named 'Janet' for a skit on Jimmy Kimmel Live! where she asked Americans what they really thought of her.

As you can imagine, public opinion out on Hollywood Boulevard wasn't great.

Despite being told she'd lost her way, that her family was annoying and that she wasn't doing anything to help the fabric of America, Cyrus didn't drop her Australian accent once.

This guy had no idea what was coming when he was interviewed by an undercover Miley for the comedy skit.

The singer, who is hosting the MTV Music Video Awards this weekend, even encouraged the random Americans to criticise her.

"Do you think her father Billy Ray raised her to be that way, or do you think she just lost her mind in all the Hollywood madness?" Cyrus asked one older woman.

"I think she lost her mind in the Hollywood madness," she replied.

One cowboy hat-wearing man told Cyrus he didn't like her whole family and thought she was empty inside.

"I think she's starving for attention and that's why she's doing it all crazy like that," he said. "She's missing something somewhere".

Added Cyrus: "In her heart, probably. In her deep soul."

The cowboy even suggested the Wrecking Ball singer shouldered some of America's woes.

"The whole fabric of America is falling apart and she's not doing anything to try to keep it together."

Despite the brown lipstick, bad wig, pearl set and frumpy grey suit, one New England Patriots supporter still knew it was Cyrus.

"You kind of look like her," he said.

Trying to keep her undercover guise for as long as possible, the singer joked she was from Perth.

"That's actually why they hired me. They flew me in from Perth and I'm here right now. I'm kind of freaking out that I'm on Hollywood Boulevard."

True to form, Cyrus then revealed she was, in fact, undercover, and as proof flashed her chest to the unsuspecting man.
