WWE Superstars John Cena and Nikki Bella have decided to go separate ways after dating for six years.

The WWE couple have announced they have called off their engagement.

"While this decision was a difficult one, we continue to have a deal of love and respect for one another. We ask that you respect our privacy during this time in our lives," read the statement.

The former couple, who got engaged last year, had been sparking break-up rumours in the latest "Total Divas" preview in which they appeared to have a second thoughts on getting married.

Cena and Bella started dating in 2012. The couple was last seen together in public at Wrestlemania 34 on April 8 and were due to get married on May 5. Last April during Wrestlemania 33, they had gotten engaged in front of a live audience.

John while speaking to Us Weekly, had admitted that the couple had been going through some "problems" and spoke about how "hard" love is in the interview.

"Don't ever think that love is easy. Love is beautiful, but we've had to come to the realisation after being together for five years that love is not easy," he said.

"We work every day on us. We have our problems just like everybody else. Some of our problems are very public, some of them aren't. But we work every day on us. Anytime I get upset, I always just realise that I can't live without her and I love her and that's why I cave in on a lot of stuff."

He also confessed that the fact their work schedules was driving a wedge between them, as they spent "months at a time" being apart.

"I think, for now at least, that is certainly what's making this work," he added.
