If there's one thing guaranteed to get fans buzzing,Tahong it's a good ol' social media exchange between two celebrities.

Millie Bobby Brown has been delivering in this area in a big way lately.

She recently shared a photo with Drake at the Golden Globes on Instagram, then posted a screengrab of a message Ariana Grande had sent her, and now -- just to top it all off -- she's been chatting to Niall Horan on Twitter.

It started when the former One Directioner tweeted about his new favourite TV show.

Then Brown, who is clearly also a fan of Horan's, responded.

The exchange then proceeded to get even more adorable.

Unsurprisingly, Twitter approved.

This was followed by the inevitable calls for Horan to guest star in the show's next season.

In a world where Harry Styles stars in the latest Christopher Nolan movie, it's not even that much of a stretch.
