Facebook is at it again - adding strange little buttons to your app without you even noticing.
The latest one to appear on people's smartphones is a little rocket ship, but don't worry if you can't actually see it on your phone.
The icon is only being trialled for select iOS and Android users. In fact, it's so select that no-one in Your Friendly Neighbourhood Digital Spy actually has the icon.
Luckily, our friends over at TechCrunch have a screenshot of what the rocket actually takes you to (not Mars, sadly) and some more info.
So, what does it do? Well, it's another trial of a secondary news feed.
This news feed is made up of people, pages and posts that Facebook's algorithms think you will enjoy. The algorithm will look at the pages you've already Liked, as well as what your friends are sharing and so on and so forth.
If this all takes off then hopefully it will mean that if you read and share stories from your favourite entertainment news website (not naming any names), then Facey-B is more likely to recommend it to your friends.
If you think this all sounds a bit familiar, Facebook trialled something similar before with the 'Explore' tab.
We've reached out to Facebook for more information, with a company spokesperson confirming: "We are testing a complimentary feed of popular articles, videos, and photos, customized for each person based on content that might be interesting to them.
"We've heard from people that they want an easy way to explore new content they haven't connected with yet."
If you want to get a little bit more out of your Facebooking, we've got 9 tips that are sure to help you out (unless Mark Zuckerberg and co completely decide to overhaul them, of course).
