John Cena is a MARRIED MAN -- tying the knot with his girlfriend Shay Shariatzadeh in Tampa, Florida ... official records show.
The couple began dating back in his early 2019, following Cena's high profile split with ex-fiancee Nikki Bella in 2018.
Cena and Shariatzadeh got very serious very quickly -- and were spotted making out all over town for the past year!
Apparently, the two got engaged on the down low -- and filed for a marriage certificate in Florida in early October.
And according to official documents obtained by TMZ Sports, they swapped "I Dos" on Oct.
