The star told the crowd:

Christina Aguilera helped a gay couple get engaged on a recent stop on her Liberation tour. The final song she performed from the album was “Unless It’s With You,” a cry-worthy piece that is sure to find its way as a staple on the wedding circuit.

Afterward, she said: “I have a really special surprise that’s happening tonight. I want to welcome two special people to the stage, Ben Lear and Mikey K,” she told a crowd that erupted in applause when they realized what was going on.

“I could not have imagined you could have a better moment than [with] this woman, who has inspired you throughout your whole life and has brought you through so many things,” Lear said to his partner.
