A new rivalry began on Monday Night Raw last week, as the Bella Twins turned on Ronda Rousey.
After aligning themselves with Rousey and Natalya on their return to the red brand in September, the Bellas took part in various tag matches to presumably shake off the ring-rust.
But it was all destined to end in a heel turn for someone, and after Rousey yet against submitted a member of the Riott Squad following their victory at Super Show-Down, the team had a babyface celebration.
That wasn't the end of it though - as Rousey turned her back, Nikki unleashed a forearm strike to the back of the Raw Women's Champion, and although the UFC Hall of Famer mounted a comeback, she would be thrown into the ring post and steel steps by the twins.
It's set up a huge match at WWE's first-ever all-women's pay-per-view - Evolution - and it's more-than-likely to be the main event of the evening on October 28.
Not because it'll be the best technical wrestling match, but because the two are probably the biggest cross-over stars in the women's division.
Rousey is an icon in Mixed Martial Arts, and has been WWE's highest-profile signing in recent memory, whilst Nikki has become a success through reality television show Total Bellas and appearing on Dancing With The Stars.
And the company know pitting the two against each other will grab more headlines than anything else.
TMZ caught up with Rousey in public this past week, and she branded the Bellas as a pair of 'untrustworthy b**ches'.
And former Divas Champion Nikki clearly caught wind of the comments, quote-tweeting TMZ with an equally-mic-dropping comment of her own.
"And she’s an undeserving b*tch. Can’t wait for RAW Philly! 💋N #Bellalution," Nikki tweeted out.
We don't know about you, but it sure seems real to us - and the 'undeserving' comment resonates with a few who people Rousey did not deserve to just walk into the company and win the title before other harder-working talent.
But a lot of people have hit back at Nikki for her tweet in savage fashion.
