Harry Styles and Millie Bobby Brown had the best time together at Ariana Grande’s concert in London this weekend and people can't get over the duo dancing together.

"The Thank U, Next" singer brought her "Sweetener" world tour to the O2 Arena on Saturday night and had a star-studded audience, thanks to Styles, 25, and Brown, 15, who were seen dancing the VIP area.

The two looked like the best of friends as they were seen walking to their designated area with Harry leading the way.

It wasn’t long before fans nearby spotted the two chatting between songs and talking into each other’s ears while laughing uncontrollably.

At one point in the video, the pair were seen showing off their dance moves as Grande performed her recent batch of hit singles. The fans were going crazy for the besties while others wondered how they could get in on the friendship.

One fan tweeted, "millie bobby brown out here laughing and joking with harry styles at an ariana grande concert and she is my age,,, where did i go wrong."

“Harry? with Millie Bobby Brown? at Ariana Grande’s concert? This just added 10 years to my life,” commented another fan.

Posting a clip of the moment, another tweeted: “So you’re telling me that Harry Styles and Millie Bobby Brown were casually chatting at the Ariana Grande concert,,, a concert I was supposed to attend… MY TWO WORLDS COLLIDED.”

Millie's "Stranger Things" role has made her very popular among her fellow celebs, even those quite older than her. For example, she has what she describes as a "lovely friendship" with 32-year-old Drake.
