It has been widely speculated that Brie Bella will battle Stephanie McMahon at SummerSlam and there could possibly be a swerve in place that sees Nikki Bella turn heel by betraying her sister.

The WWE has built up a struggle between McMahon and Brie Bella over the last few months as Brie has been arguing with McMahon over her mistreatment of former WWE World Heavyweight Champion Daniel Bryan, who is Brie's husband and is out with a neck injury for an unknown period of time.

The storyline led to Bella quitting the WWE and has seen McMahon kick her out of the backstage area for turning her back on the company. On top of that, McMahon has also mistreated Nikki in retaliation and even put her in a four-on-one handicap match on last week's Monday Night RAW.

Prior to that match, McMahon came out and slapped Brie -- who was at ringside as a fan -- and was subsequently arrested for assault on the program to continue the build to the McMahon vs. Brie match at SummerSlam on Aug. 17 at the Staples Center in Los Angeles.

According to Wrestlingheadlines.com, there has been continuous talk of turning Nikki heel and if the WWE decides to go through with it, it would be at the conclusion of Brie's feud with McMahon. Brie vs. McMahon is scheduled for SummerSlam, so it is possible that the company will opt to turn Nikki then but it remains to be seen.

It is expected that the stipulation will be that Brie gets her job back if she beats McMahon. Nikki may not turn on her at the pay-per-view, but it could come within the next few months if the WWE does pull the trigger on it. How a heel turn would affect the next Total Divas season and Bella's well-known relationship with top babyface John Cena remains to be seen.

The only official match announced for SummerSlam so far is Cena vs. Brock Lesnar for the WWE World Heavyweight Championship in the main event.

Other rumored matches include Chris Jericho vs. Bray Wyatt and Roman Reigns vs. Randy Orton as Jericho and Wyatt have been feuding and will have a rematch from Battleground and Reigns attacked Orton on RAW.

There is also a possible match between WWE Intercontinental Champion The Miz and WWE United States Champion Sheamus being speculated, and it may even be title-for-title.

While nothing is set in stone, it is possible that Nikki turns on Brie sometime in the next few months.
