Looks like J.Lo has learned the art of the fake out from Ryan Seacrest. If you watched Today this morning, you, like us, were patiently waiting for the American Idol judge—thought to be signing on for season 11 any day now—to make her mysteriously "BIG ANNOUNCEMENT." At least after host Ann Curry hyped her appearance as such. (Big mistake, Ann. Huge.) In reality, Lopez was simply on air to promote/endorse/promote some more for the product placement-heavy new concert from iHeartRadio, keeping quiet on her Idol-related thoughts all together (which at this point, shouldn't surprise us). Watch the cruel tease, below (made even worse if you haven't had your coffee yet).
