Ryan Cabrera and Alexa Bliss agree with Beyonce ... if ya like it, you should put a ring on it -- that goes for men and women, which is why he's already rocking a "man-gagement" ring.
The singer and WWE superstar were at LAX Wednesday when a photog noticed they were both wearing rings as they clutched their iced coffees. He asked the obvious ... did they already get married? But, they explained it's not what it seems.
Ryan says the band is his engagement ring from Alexa, and she says they want to normalize this practice.
