Move over, Taylor Swift! Madonna enlists Katy Perry, Beyonce and more for all-star music video

Hot on the heels of Taylor Swift's star-studded 'Bad Blood' video, the original pop queen Madonna has recruited her own A-list dream team for her upcoming video for 'Bitch I'm Madonna' (see the mysterious Instagram teaser above).

And guess what? The line-up features Taylor's nemesis, and the rumoured subject of 'Bad Blood', Katy Perry! Madonna also roped in Beyonce (we're actually losing our shizzle over this), Miley Cyrus, Nicki Minaj and Rita Ora.

The 56-year-old shared a poster promoting the clip, mimicking the same black-and-red, Tarantino-esque teaser posters of Taylor's 'Bad Blood' promo campaign. But hey, she's Madonna and she can anything she likes.

Hang on, we thought Madonna was #TeamTaylor after they performed together at the iHeartRadio Music Awards in March? Is she siding with Katy or just being her cheeky, headline-grabbing self? The video is due out in the next 24 hours so we'll know soon.

For now, check out Madonna and Taylor below. We hope this isn't the start of a new feud…
