Christina Aguilera sent Twitter wild Wednesday night as she turned out to be the surprise guest at a gig at Dublin’s 3Arena.

The 37-year-old, who shared a snap earlier in the day of herself wandering the Irish capital’s streets, took the stage to perform some of her biggest hits.

She was even joined by her two children Max and Summer at one point, with fans sharing clips of the epic performance online.

Later that night, Xtina was caught on camera dancing the night away to her smash hit “Dirrty” at Xico nightclub:

The singer, who has been busy promoting her new album Liberation, recently spoke about her latest music on Beats 1 on Apple Music.

“These songs so make sense and are so relevant now,” the Grammy winner stressed. “I was doing it back then and I’m glad that I stuck to my guns. I really truly just came out with things that I believed in, even if it was against the grain, and even if people were like, ‘Really, you shouldn’t be saying that. It’s going to start up too much controversy.’”
