Miley Cyrus will host this year's MTV Video Music Awards (VMAs).

Taking to social media, the former Hannah Montana star announced her new gig by sharing a picture collage of herself dressed as a green alien and holding a two sandwich boards.

The first board reads: "MTV won't let me perform", while the second says: "So I'm hosting this year's VMAs".

The 25-year-old pop star's return to the stage comes two years after she shocked audiences with her raunchy performance with Robin Thicke back in 2013.

The segment, which featured a scantily clad Cyrus twerking on the then-married Blurred Lines hitmaker and grabbing his crotch, sparked outrage and triggered complaints from parent groups and TV regulators.

Although it was reported that Paula Patton felt "utterly disrespected" by her then-husband's antics, the Mission Impossible star claimed that she was bemused by the public condemnation of the routine.

"Honestly, they rehearsed for three days beforehand and I don't know how not to dance with someone having their booty in your... all my friends do it like that! I don't really know what the big deal is," she said.

Thicke also defended the show, telling Oprah Winfrey that it was fun rather than sexy.

"I just said, I don't care, let's entertain the people. Let's give them something they're not ready for, let's make them talk," he told the chat show queen during an interview.

"So to me, I'm walking out towards Miley, I'm not thinking 'sex', I'm thinking 'fun'," the Blurred Lines singer explained.

In 2014, Cyrus took a different approach when she won the video of the year prize for Wrecking Ball. Rather than get on stage herself, she invited a homeless teenager named Jesse to accept the award on her behalf.

The 2015 VMAs will air live 30 August at 9pm EST on MTV.
