As Hurricane Harvey sputters out, JJ Watt's relief fund is heating up, hitting the 20 million mark today.
J.J.'s crowdfunding campaign started off with a goal of $500K a little over a week ago ... and quickly ran up into the multi-millions with big-name celebs and athletes like Miley Cyrus ($500K), Drake ($200K) and Chris Paul ($75K) leading the way.
JJ's younger bro TJ, is a Steelers rookie this year on the defense. Both seem like stand-up dudes.
