WWE shared video of Cena popping the question:
The proposal came after he and Nikki beat The Miz and his wife, Maryse, in a tag-team match.
The Wrestling Observer's Bryan Alvarez joked it finally answered one of the biggest questions about Cena's in-ring career:

Cena's failure to propose earlier was a part of the rivalry that led him and Nikki to cross paths with The Miz and Maryse at WrestleMania. During the buildup to the show, The Miz and Maryse ridiculed the couple and said Cena loved himself rather than Nikki:
Not only will Cena's proposal be a patented WrestleMania moment, but it could be a fitting send-off for Nikki, much like when her sister Brie was carried around the ring at WrestleMania 32 before leaving the company.
Nikki said Saturday she will take time off to heal a herniation in her surgically repaired neck, per Brad Davis of SEScoops.
WWE fans will also likely see little of Cena in the coming weeks. Wrestling Observer Radio's Dave Meltzer (h/t WrestleZone's Nick Paglino) reported in February the 16-time world champion is taking time off to film The Pact.
