Brady, 41, jokingly announced his retirement, and said he would spend the rest of his time tweeting.
Some believed his joke to be legit, and some fans had a meltdown. They were relieved when Brady sent a follow-up tweet a few hours later.
The six-time Super Bowl Champion has always been a Facebook and Instagram guy. But he's been strangely absent from Twitter.
A Twitter spokesperson confirmed the authenticity of the account.
Brady led the Patriots to another Super Bowl title earlier this year and shows no signs of slowing down.
