John Cena and Nikki Bella may be at war based on the latest tweets from the two WWE stars. The ex-couple posted two cryptic tweets that seem to be aimed at each other and their breakup, which happened nine months ago.

Cena seemed to have started the rivalry between the two as he posted on Twitter on Monday, “Beware those who think you owe them happiness at the expense of your own well being.”

Bella didn’t let these comments lie as she responded with her own message on Twitter on Tuesday that read, “When you don’t give him what he wants, he will delete you, silence you, manipulate you, do what he can to destroy you, but turn that hurt into strength. Take the high road and prevail! Happiness can’t be bought, it is priceless. It’s your true secret weapon. N.”

Cena came back with another response on Wednesday that read, “It’s very easy to shift blame for our own mistakes. Own your everything”

Bella has since moved on from Cena with her “Dancing With the Stars” partner, Artem Chigvintsev. Cena has also moved on with a new lady in his life, Shay Shariatzadeh.

Cena and Bella ended their engagement in April 2018. They were together for six years.
