There is another reliable report out regarding the planned WWE Evolution main event. According to the Wrestling Observer, Raw Women’s Champion Ronda Rousey will face Nikki Bella in the headline match of WWE’s historic all-women’s pay-per-view.

“The lead idea for the Evolution main event on 10/28 at the Nassau Coliseum is Rousey vs. Nikki Bella,” wrote Dave Meltzer. “With the idea you are headlining with the two biggest mainstream women stars in the company.”

Over the past week, we’ve seen The Bella Twins return to WWE television and Ronda Rousey capture the RAW Women’s Championship. At both SummerSlam and Raw, the Bella Twins have had stood alongside Rousey in celebrating her championship victory.

WWE Evolution takes place on Sunday, October 28th from Long Island, New York at the Nassau Coliseum. Expect to see more interactions between Rousey and the Bellas in the coming weeks. The Bellas have been supportive of Rousey thus far. It will be interesting to see how and when things go sideways.

The storyline may have already started to take shape this week. The Bellas were ringside during Rousey’s segment with Stephanie McMahon on Raw. They were also shown watching Rousey win the title at Summerslam.

The Bellas and Rousey are not strangers. The Bellas would sometimes train with Ronda when they were in California before Rousey got into the business herself. Rousey and her team would teach the twins MMA and judo moves, while the Bellas taught them wrestling moves. The Bellas and Rousey appeared together at the 2015 ESPY awards as well.

In 2015, Nikki told TMZ reporters she would love to face Ronda some day.
