Another one bites the dust.

John Cena and Nikki Bella have decided to end their engagement and breakup just weeks before their wedding, and more than six years after they first started dating in 2012.

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

So what went wrong?

"She never gave him an ultimatum. He talked a really good game about having changed, about having his priorities straight, about knowing what’s important, and that it was her. But as the day got closer, it was like he just went back to who he’s always been — which is someone who puts himself first, always. He’s an incredibly dedicated, driven, ambitious guy. And for the longest time he said he didn’t think he had room in his life for a spouse or kids. It seems like in the end that was still the truth," a source dished to People.

"But in that case, he never should’ve proposed, let alone in front of millions of people. Now she’s heartbroken. This was supposed to be the happiest time of her life. He ruined it and blew everything up," the source added.

The Blockers star shared this message on social media just as the news was breaking.

"Hardship, loss, and humility are extremely difficult waters to navigate, but perseverance thru them builds a strength to withstand anything life throws your way," he wrote.

Cena, 40, proposed to Bella, 34, at Wrestlemania in April 2017, and their wedding was set for May 5 in Mexico.
