Harry Styles and Millie Bobby Brown Dance Together at Ariana Grande Show

The 'Sweetener World Tour' has a few VIPs in London

Ariana Grande has taken her Sweetener World Tour to Europe, starting her run with a string of shows in London at the O2 Arena and a few very special guests.

In clips posted this weekend, Grande belts out “Dangerous Woman” as Harry Styles and Stranger Things star Millie Bobby Brown are spotted dancing together in the crowd. Later as Ariana performed “Break Free,” the two bounce around the section completely committed to the groove.

The 15-year-old star and the “Sign of the Times” singer made the most of their night out, catching a vibe courtesy of Ariana Grande.

After dancing side by side, the pair finally slowed down long enough to have a conversation. The two were captured chatting later in the show, before Styles was approached for pictures by fans.

Millie meanwhile was busy with her own squad.

The Sweetener World Tour will continue making its way across Europe into October, returning to the states in November for another string of shows. You can find the full list of upcoming dates here.
