Katy Perry is set to open this year's MTV VMAs.

She is currently in talks with organisers, who are hoping she will address her high-profile feud with Taylor Swift, which was brought back into the limelight yet again last week.

A source told The Sun newspaper: "Katy's been gearing up for her musical comeback for months and this would be the perfect way to launch herself back on the big stage. The talks are in early stages but both parties are keen for it to happen.

"Her record label Capitol have backed her by coughing up millions to ensure her new album is her best yet. Given the amount of material she has at her disposal, especially her reaction to Taylor's diss track 'Bad Blood', you can see why it's so highly anticipated."

Katy and Taylor fell out in 2012 when Katy allegedly stole one of Taylor's backing dancers for her 'Prism' tour.

Taylor, 26, then hit back by basing her song 'Bad Blood' on their fall out.

Last week, Katy found herself embroiled in a battle again after Taylor's ex-boyfriend Calvin Harris hit out at his former lover on Twitter.

He tweeted: "I know you're off tour and you need someone new to try and bury like Katy ETC but I'm not that guy, sorry."

Soon after his rant, Katy retweeted a message she wrote in May 2015 which read "time, the ultimate truth teller".

The raven-haired beauty also shared an animated gif on Twitter of US presidential candidate Hillary Clinton pulling a smug "I told you so" expression.
