The cast of the Fox series concluded their summer concert tour in Dublin, Ireland on Sunday, and Morris, acting as her ditzy character Brittany, went on the hunt for someone to kiss. After Blaine (Darren Criss) declined, Rivera came on stage as her character, Santana, and gave her Brittany a kiss.
Fans of the series' will-they-or-won't-they lesbian couple were so delighted, "They Kissed" began trending worldwide on Twitter.
Not to be upstaged, Chris Colfer's Kurt came onstage to recite a poem to love interest Blaine. Shortly thereafter, Criss grabbed Colfer's face and brought him in for an equally cute lip-lock.
Check out video of the two kisses (the ladies at 1:35, the boys at 4:34):
