This question already has an answer here:
Here is my transaction: https://blockchain.info/tx/3ddd5a173a73fc82bb0e1eb4361b8c36eb65919e2bfb9ee78fe2c6b5ff3f2307
I only sent .003 BTC to 1 address (35iR3hnFqmkHswRm8PmZgTKxYm7GfucNZJ), but the transaction shows BTC being sent to 2 addresses. This is exactly what happened to me one month ago with another transaction: https://blockchain.info/tx/672744cd9a355b908fbf256680726e96279c13a8c39770a30a472c25371c6798
Since you guys tend to be pretty cynical (meaning you're smart) I have attached a screenshot as proof that I did not try to send the transaction to 2 addresses.
