Alberto Del Rio & Paige's Love is 100% Real

Alberto Del Rio and Paige say they're sick and tired of people talking smack about their relationship ... assuring the whole love-hating world that their romance ain't for show ... and they got the tats to prove it.

The happy couple were out in NYC when our camera guy asked why everyone is so interested in whether or not they are actually banging ... or just faking for Paige's "Total Divas" reality show.

Check out the clip -- Paige and ADR give all their haters the business ... saying the feels between them are so legit ... they went and got each other's names tatted on their body (always a smart move).
