More than three years after his season of "American Idol" ended, Adam Lambert's hair, both on his head and on his face, remains the hot topic of much online debate. Elvis hair or emo hair? Blue Manic Panic stripe or Vanilla Ice stripes? Clip-on ponytail or no? Goatee or beard-free? There was even one time when he tweeted a pic of the side of his head freshly shaved, and Twitter basically exploded. Well, the engineers over at Twitter better have some backup servers in place, just in case, now that the forever-shapeshifting Glamerican Idol has just tweeted another photo of what may be his most extreme follicle makeover yet.

The Muppets take over "The Voice"If there was one thing that could improve upon "The Voice's" Adam/Xtina/Blake/Cee Lo formula, it would be having the judges rendered in puppet form. (I am a steadfast believer that puppets make everything better, and my obsession with all things felt has been well-documented in the past.) The geniuses over at "Sesame Street" recently posted a preview of their new "Voice" parody, and it's just as adorable and amazing as one might expect.

The Muppet Christina is infinitely more likable than the flesh-and-blood one. The Carson Daly puppet seems more lifelike and charismatic than the real guy. Oddly, there's no Adam Levine puppet...but otherwise, this clip is just about perfect. There's even a Muppet version of Cee Lo's feline mascot, Purrfect!

photo: NBCAfter cryptically tweeting recently that she was ready to quit "America's Got Talent," Sharon Osbourne officially announced her resignation from "AGT" this week, after a seven-season run. While at first fans might have assumed that she was leaving due to some sort of feud with new judge Howard Stern, it turns out her feud is actually with NBC executives, over what she claims was discrimination against her ailing son, Jack. And now Sharon has made her war with the network public, via a slew of typically outspoken, scathing comments to The New York Post. It seems hell hath no fury like a mama Osbourne scorned.
