The 39-year-old star got down on one knee after he and Bella won the mixed tag team match at the wrestling event in Orlando.
"I have been waiting so long to ask you this. Stephanie Nicole Garcia-Colace, 'Will you marry me?'," he asked his lady.
After Bella tearfully said yes, the couple shared a sweet embrace and a kiss as the WrestleMania crowd cheered their approval.
The proposal took Bella by surprise, but Cena's social media posts leading up to the WrestleMania event hinted at his plans to propose her.
Bella's sister, Brie, also congratulated the pair, writing "Happy tears!!! They always felt married to me but to see it...Wow!!! Welcome to the family @JohnCena.
