Will she or won't she?

Rumours are rife here in Amsterdam that musical enfant terrible Miley Cyrus, who provoked an international storm with her twerking performance at the MTV Video Music Awards, is poised to take things one stage further when she appears at the Europe Music Awards on Sunday night.

A source close to the awards suggested the singer will go topless at some point during her act at the Ziggo Dome, which will be broadcast to a global TV audience of about 700 million people.

Cyrus, 20, is expected to perform Wrecking Ball live. A video of the song showing her completely naked and clinging to a chain is already an online sensation.

It is known that the former Hannah Montana TV child star had planned to flash her breasts during August's VMA raunchy twerking routine with Robin Thicke, when she stripped to latex underwear for a performance of another song, We Can't Stop.

Cyrus told Britney Spears in a US TV documentary last month that going topless was vetoed by MTV bosses.

However, one suggestion is that the organisers may be more relaxed in a European venue, rather than New York, where the VMA was staged.

A reading of official pre-publicity has added to the hype around the Amsterdam performance by Cyrus.

Bruce Gillmer, co-executive producer of Sunday evening's event, told the Hollywood Reporter: "Miley is always looking to break creative boundaries. You can count on her not doing the same thing twice.

"She will figure out another way to blow people's minds."

Gillmer added that the EMA team tries "not to script things too heavily," insisting: "We like to let moments happen. We have very dynamic personalities in one room who bring their own energy to the event."

Cyrus, who arrived in Amsterdam on Thursday, told MTV News she planned a very special EMA performance of Wrecking Ball.

"I've had this vision for a while; I've wanted to somehow involve something around aliens - because I really love aliens?¦ I built the show around aliens. What I'm all about?¦ is just having fun on the show, and not doing anything too serious."
