The couple announced their break-up on Sunday evening, putting an end to their engagement. They said in a statement, "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."
Us Weekly was the first to report the split.
The couple was together for six years and Cena proposed to Bella last year at Wrestlemania.
As recently as earlier this month, looked insanely in love as they walked the red carpet together for the premiere of Cena's movie, "Blockers."
