Rihanna has reportedly weighed-in on the whole Katy Perry Vs. Taylor Swift feud, with reports claiming the Bajan babe is planning her very own T-Swizzle diss track! WUT.

According to US OK! magazine, the ‘B*tch Better Have My Money’ singer is tired of Tay poking fun at her BFF K-Pez (hello, left shark shade!) and has decided to take matters into her own hands.

It’s thought that RiRi is also NOT a fan of Taylor’s star-studded ‘Bad Blood’ music video and the same can be said for her “good girl” image.

A source explained: “Ri’s protective of Katy and bugged by Taylor’s growing good-girl clique”, before adding that she’s planning to record a song about “kiss and tell” women and that it will be an “aggressive club anthem with a video that’s just as brutal as ‘Bad Blood’.”

The insider adds that when the promo drops, “it’ll be very obvious that it’s about Taylor.”Meow!

Apparently, RiRi hasn’t informed Perry about the song or video, but the ‘Dark Horse’ singer “is aware that Rihanna wants to do something.”

Despite the danger of ticking off Tay’s army of fans, Rihanna’s “not worried”, with the source concluding: “She knows Taylor’s intimidated by her.”

After seeing RiRi’s ‘BBHMM’ promo, we’d be a tad concerned if we were Swifty! Here’s hoping her 'We Found Love' collaborator (AKA Taylor’s beau)Calvin Harris can stop this madness…
