We all know that what we post on the internet stays on the internet forever — and that's especially true for celebs. The fun thing about that is sometimes it means you can uncover very wholesome tweets from celebrities before they were mega-famous that have a whole new meaning now. Take this Sabrina Carpenter tweet from when she was 11 years old, for example:

Now Sabrina will be opening for Taylor Swift on the Latin American leg of her MASSIVE Eras Tour.

This kind of thing actually happens a lot more often than you'd think, so here are 20 more examples:
