Sure, Halsey has a show at London's Wembley Stadium on Saturday (June 8), but why not make a quick pit-stop at BTS' show in Paris first?

The pop star recently surprised fans in the French capital when she came out at BTS' concert at Stade de France. According to one fan, Halsey said, "These boys are so special... they are my family," in French after performing their hit single "Boy With Luv."

The superstar group also performed their smash hit together at the Billboard Music Awards in May.

Check out some of the Paris performance via fan tweets below.
