Lana has finally addressed this.

The SmackDown star was recently a guest on 107.7 The Bone with Baby Huey & Bimbo Jimbo. During the interview, she spoke about rumors of her having backstage heat with other superstars. 

Lana signed with WWE in June of 2013 and was sent to their developmental branch NXT. Rusev, on the other hand, signed with WWE in September of 2010 and was assigned to WWE's Florida Championship Wrestling developmental territory in Tampa, Florida, where he adopted the ring name Alexander Rusev.

She debuted on the October 23, 2013 episode of NXT by scouting Alexander Rusev. The following month, WWE put her as Rusev’s manager on television. They had a short run while in the developmental brand.

Lana made her main roster debut on the January 31 episode of SmackDown where she and Rusev in the following weeks appeared in a series of self-promotional videos and speeches.

Fast forward to May of that year; they made their television debut. WWE has kept both Rusev and Lana strong on television. Rusev would end up winning the United States Title while with her.

Fast forward, WWE did a breakup angle after Lana quit on Rusev’s behalf during an I Quit Match with John Cena at the Payback PPV event in 2015. There was a brief storyline where Lana was aligned with Dolph Ziggler against Rusev.

In October of that year, TMZ reported that Lana had gotten engaged to Rusev, which Lana confirmed. This led to Lana making her return to WWE TV as a villainess and by Rusev’s side. WWE then took her off of TV until February of 2016 where she was pushed as a singles star.

Lana faced off with Brie Bella in a tag team match on the WrestleMania 32 pre-show. This would be Lana's in-ring debut. After this match, WWE once again put her with Rusev until they were drafted to SmackDown Live earlier this year. There is a trend here. When Lana and Rusev are together, they have success, but when separated, not so much.

The possible heat was due to their engagement getting out. She made it clear that there was no heat as WWE Chairman Vince McMahon made the call to the change the storyline. Here is what she had to say (transcript courtesy of IWNerd): 

“The truth was that Vince McMahon just decided to go a different route, and that’s just what it was. Rusev and I were trending for like three days straight “Rusev and Lana are engaged”.

He just made the decision at that time he goes ok I want to bring them back together…People are always going to talk. I think for 6 months after that the headline was Lana has nuclear heat, (laughter) and I am like great! You know, you’re talking about me.”

When asked about how Rusev felt about being on Total Divas, she stated, “He definitely wanted to do it. He fully supports me, and so he was excited to do it. He’s a character. He’s so funny.
So, he’s just himself on that like

Sure if cameras want to follow me around that’s fine. I might just be naked at my pool. It’s not my fault the cameras are here. Which you guys are going to have to watch Total Divas. That might happen next week.”
