As if you needed any more proof John Cena and Shay Shariatzade are "official" -- here's Cena DROPPING HER OFF AT THE AIRPORT ... and even giving her a kiss goodbye!
An eagle-eyed traveler spotted the WWE superstar at the San Diego Airport on Wednesday -- sharing a kiss and loving embrace with his rumored girlfriend before she caught a flight back home to Canada.
But, c'mon -- look at these two!!! They're definitely serious now!!!
We spotted the two out on a date last month -- and clearly things have escalated because what grown person takes someone to the airport these days if you're not romantically involved?
