The fact alone that he's 46 years old and he's yet to sprout a mustache is reason enough not to trust Jay-Z, but now there's also his Tumblr.
Jay-Z himself obviously doesn't have anything to do with updating. Not even one post, to make it seem like hes at least aware that he has a Tumblr. Worse, these posts just look like ads that don't carry any disclaimer stating that they are in fact ads.
One of them is an interview with someone who works for Jeep, with whom, I seem to recall, Jay-Z has had a business relationship. Are we supposed to believe Jay-Z likes to go 4-wheeling? The nigga grew up in the Marcy Projects!
